New BmpViewerActivity opens, parses, and renders BMP files with centered
aspect-ratio-preserving display and localized back navigation. Library
file filter extended to include .bmp. ReaderActivity routes BMP paths to
the new viewer. LyraTheme button hint backgrounds switched to rounded
rect fills to prevent overflow artifacts.

Rewrite README.md to distinguish the mod fork from upstream CrossPoint
Reader. Add mod feature documentation (bookmarks, dictionary, clock, book
management, table rendering, reader menu overhaul, etc.), updated feature
checklist, upstream compatibility notes, and mod-specific build instructions.
Bump version from 1.1.1-rc to 1.1.2 to align with upstream approaching
release.

Add '/' as explicit hyphen delimiter and relax the alphabetic-surround
requirement for '/' and '-' in buildExplicitBreakInfos so URL path
segments can be line-wrapped. Includes repeated-separator guard to
prevent breaks between consecutive identical separators (e.g. "http://").

- Fix device freeze at end-of-book by deferring EndOfBookMenuActivity
creation from render() to loop() (avoids RenderLock deadlock) in
EpubReaderActivity and XtcReaderActivity
- Add initialSkipRelease to BookManageMenuActivity to prevent stale
Confirm release from triggering actions when opened via long-press
- Add initialSkipRelease to MyLibraryActivity for long-press Browse
Files -> archive navigation
- Thread skip-release through HomeActivity callback and main.cpp
- Fix HomeActivity stale cover buffer after archive/delete by fully
resetting render state (freeCoverBuffer, firstRenderDone, etc.)
- Swap short/long-press actions in .archive context: short-press opens
manage menu, long-press unarchives and opens the book
- Add deferred open pattern (pendingOpenPath) to wait for Confirm
release before navigating to reader after unarchive
- Add BookManager::cleanupEmptyArchiveDirs() to remove empty parent
directories after unarchive/delete inside .archive
- Add optional unarchivedPath output parameter to BookManager::unarchiveBook
- Restyle EndOfBookMenuActivity to standard list layout with proper
header, margins, and button hints matching other screens
- Change EndOfBookMenuActivity back button hint to "« Back"
- Add Table of Contents option to EndOfBookMenuActivity

## Summary
* **What is the goal of this PR?** (e.g., Implements the new feature for
file uploading.)
Implements new feature for viewing .bmp files directly from the "Browse
Files" menu.
* **What changes are included?**
You can now view .bmp files when browsing. You can click the select
button to open the file, and then click back to close it and continue
browsing in the same location. Once open a file will display on the
screen with no additional options to interact outside of exiting with
the back button.

## Additional Context
* Add any other information that might be helpful for the reviewer
(e.g., performance implications, potential risks,
specific areas to focus on).
The changes implemented in #884 are also present here as this feature is
actually what led to me noticing this issue. I figured I would add that
PR as a separate request in case that one could be more easily merged
given this feature is significantly more complicated and will likely be
subject to more intense review.

EpubReaderMenuActivity now shows "Manage Book" instead of "Delete
Book Cache". Selecting it opens BookManageMenuActivity as a sub-activity
with Archive, Delete, Delete Cache, and Reindex options. New menu
actions (ARCHIVE_BOOK, DELETE_BOOK, REINDEX_BOOK, REINDEX_BOOK_FULL)
are forwarded to EpubReaderActivity and handled via BookManager.

BookManager provides static functions for archive/unarchive/delete/
deleteCache/reindex operations on books, centralizing cache path
computation and file operations. Archive preserves directory structure
under /.archive/ and renames cache dirs to match new path hashes.
RecentBooksStore: :clear() added for bulk cache clearing use case.

Reduces ParsedText::layoutAndExtractLines CPU time 5–9% via two
independent optimizations from jpirnay's PR #1027:
- 128-entry direct-mapped word-width cache (4 KB BSS, FNV-1a hash)
absorbs redundant getTextAdvanceX calls across paragraphs
- Early exit in hyphenateWordAtIndex when prefix exceeds available
width (ascending byte-offset order guarantees monotonic widths)
- Reusable prefix string buffer eliminates per-candidate substr allocs
- Reserve hint for lineBreakIndices in computeLineBreaks
List-specific upstream changes (splice, iterator style) not applicable
as mod already uses std::vector (PR #1038). Benchmark infrastructure
excluded (removed by author in final commit).

Replace per-pixel drawPixel calls with byte-level framebuffer writes
for fillRect, axis-aligned drawLine, and fillRectDither. Adds
fillPhysicalHSpanByte/fillPhysicalHSpan helpers that write directly
to physical rows with memset and partial-byte masking.
Also applies coderabbit nitpick: fillPolygon scanline fill now uses
fillPhysicalHSpan for Landscape orientations.

When auto-sleep triggers after inactivity, the CPU remains at 10 MHz

When the selected row's filename overflows the available text width
(with extension), the row expands to 2 lines with smart text wrapping.
The file extension moves to the second row (right-aligned). Non-selected
rows retain single-line truncation.
Key behaviors:
- 3-tier text wrapping: preferred delimiters (" - ", " -- ", en/em-dash),
word boundaries, then character-level fallback
- Row-height line spacing for natural visual rhythm
- Icons aligned with line 1 (LyraTheme)
- Pagination uses effectivePageItems with anti-leak clamping to prevent
page boundary shifts while ensuring all items remain accessible
- Boundary item duplication: items bumped from a page due to expansion
appear at the top of the next page, guarded against cascading

Port three new upstream commits and align the existing #1002 port:
- PR #1014: Strip unused CSS rules by filtering unsupported selector
types (+, >, [, :, #, ~, *, descendants) in processRuleBlockWithStyle.
Fix normalized() trailing whitespace to also strip newlines.
- PR #1018: Add deleteCache() to CssParser, move CSS_CACHE_VERSION to
static class member, remove stale cache on version mismatch, invalidate
section caches (Storage.removeDir) when CSS is rebuilt. Refactor
parseCssFiles() to early-return when cache exists.
- PR #990: Adapt classic theme continue-reading card width to cover
aspect ratio (clamped to 90% screen width), increase homeTopPadding
20->40, fix centering with rect.x offset for boxX/continueBoxX.

## Summary
* In a sample book I loaded, it had 900+ CSS rules, and took up 180kB of
memory loading the cache in
* Looking at the rules, a lot of them were completely useless as we only
ever apply look for 3 kinds of CSS rules:
* `tag`
* `tag.class1`
* `.class1`
* Stripping out CSS rules with descendant, nested, attribute matching,
sibling matching, pseudo element selection (as we never actually read
these from the cache) reduced the rule count down to 200
## Additional Context
* I've left in `.class1.class2` rules for now, even though we
technically can never match on them as they're likely to be addressed
soonest out of the all the CSS expansion
* Because we don't ever delete the CSS cache, users will need to delete
the book cache through the menu in order to get this new logic
* A new PR should be done up to address this - tracked here

Use double FAST_REFRESH for image pages to prevent grayscale washout,
HALF_REFRESH sets e-ink particles too firmly for the grayscale LUT to
adjust, causing washed-out images (especially large, light-gray ones).
Replace HALF_REFRESH with @pablohc's double FAST_REFRESH technique:
blank only the image bounding box area, then re-render with images. This
clears ghosting while keeping particles loosely set for grayscale.

## Summary
* ``renderChar`` checked ``is2Bit`` on every pixel inside the inner
loop, even though the value is constant for the lifetime of a single
glyph
* Moved the branch above both loops so each path (2-bit antialiased /
1-bit monochrome) runs without a per-pixel conditional
* Eliminates redundant work in the two inner loops that render font
glyphs to the frame buffer, targeting ``renderChar`` and
``drawTextRotated90CW`` in ``GfxRenderer.cpp``
## Additional Context
* Measured on device using a dedicated framebuffer benchmark (no display
refresh). 100 repetitions of "The quick brown fox jumps".

1. `RecentBooksActivity::loop()` calls
`onSelectBook(recentBooks[selectorIndex].path)` - passing a
**reference** to the path
2. `onSelectBook` is `onGoToReader` which first calls `exitActivity()`
3. `exitActivity()` triggers `RecentBooksActivity::onExit()` which call
`recentBooks.clear()`
4. The string reference `initialEpubPath` is now a **dangling
reference** - the underlying string has been destroyed
5. When the reference is then used in `new ReaderActivity(...)`, it
reads garbage memory
6. The same issue occurs in `HomeActivity` at line 200 with the same
pattern
The fix is to make a copy of the string in `onGoToReader` before calling
`exitActivity()`, so the path data persists even after the activity
clears its data structures.

Cherry-pick upstream commit 07d715e which refactors renderChar and
drawTextRotated90CW into a template-based renderCharImpl, hoisting
the is2Bit branch outside inner pixel loops for 15-23% speedup.

## Summary
The introduction of `HalGPIO` moved the `BatteryMonitor battery` object
into the member function `HalGPIO::getBatteryPercentage()`.
Then, with the introduction of `HalPowerManager`, this function was
moved to `HalPowerManager::getBatteryPercentage()`.
However, the original `BatteryMonitor battery` object is still utilized
