Store per-page paragraph indices in section cache to enable precise
XPath-to-page and page-to-XPath mapping without reparsing XHTML.
Forward path (upload): generates XPath directly from paragraph LUT
instead of byte-offset estimation, eliminating drift in chapters
with non-uniform content density.
Reverse path (download): resolves incoming KOReader XPath p[N] to
the exact page via paragraph LUT lookup.
Paragraph counter counts all <p> elements including display:none
to match ChapterXPathIndexer and crengine's standard XPath counting.

## Summary
**What is the goal of this PR?**
This change deletes include/README, which is a PlatformIO boilerplate
placeholder file explaining what header files are. The include/
directory isn't used by this project (headers live in lib/ and src/), so
this is just cleanup.

## Summary
* A simple tweak to pre-index the next chapter silently during normal
reading.
* Triggers silent pre-indexing of the next chapter when the penultimate
page of a chapter is rendered to reduce visible interruptions.
* Keeps existing indexing with popup when a reader jumps directly into
an unindexed chapter.
## Additional Context
* Reader input is temporarily blocked during silent indexing to avoid
navigation/index state conflicts.
* The penultimate page is used because readers typically spend longer
there than on the final page.
* This change optimizes linear reading flow while preserving reliable
indexing for non-linear navigation.
## Possible Improvements
* Add a setting for First Page Indexing vs Penultimate Page Pre-indexing
* Display an indexing icon in the status bar instead of using a popup
that overlaps book text.

## Summary
* **What is the goal of this PR?** All praise goes to @didacta for his
PR #537. Just picked up the reviewer comments to contain the changes as
suggested (there was no response for more than 6 weeks, so I wanted to
reanimate this feature).
Just one addition: should recognize usb cable plug ins / retractions and
update the icon immediately
* **What changes are included?**
## Additional Context
see #537
