Integrate rebuilt reader and preserve open book sessions

[Eoic]

Ticket

Summary

Update the Git-pinned reader to e9f91aa1a6fd6a93494e7aeba057f6f65c6e1c18, bringing rebuilt EPUB/PDF engines, responsive settings, correct reading appearance and distraction-free controls into the client.

Retain one ReaderDocument per open book so a host theme rebuild preserves the session instead of reopening and rereading its media. The media-loading screen now exposes Back. Regressions cover document identity/media reuse and popup/label contrast across real light, dark and e-ink themes, compact/wide layouts and live appearance changes.

Testing

Against the published Git dependency: enforced lockfile resolution, 23 focused reader-related client tests, formatting/analysis, four web-bootstrap tests and a web release build passed. Reader validation includes 144 tests, example checks and the Chrome worker/layout/focus/theme/resume suite.

For manual review, open EPUB and PDF books, change the app and reading themes independently, open settings menus, hide/show the controls, navigate across chapters with arrow keys, and test compact/wide layouts and PDF pagination/scroll/columns.

UI evidence

Local Chrome screenshots were visually reviewed for phone focus mode and reading settings with opposite host/reading themes; no screenshot attachments are included in this PR.

Compatibility and migration

No local path override is included. The dependency points to an immutable, already-pushed reader commit. Stored reader locator JSON remains compatible; no database migration is required.

Notes

Depends on reader PR #3. Merge reader, then client, then the workspace references. Device and cross-browser release validation remain follow-up work.
