Add Calibre-parity search modes to the reader's full-text search. The
"Match Whole Words" toggle becomes a single-select mode group: Contains,
Whole Words, Regular Expression, Nearby Words.
- Regex and nearby-words matching live in the foliate-js submodule
(bumped here); the sidebar threads `mode` and `nearbyWords` through.
- Nearby distance is chosen with a "within N words" control (5/10/20/50,
default 10), not parsed from the query, so trailing numbers stay
literal search words.
- Per-mode modifiers: Match Diacritics is greyed out for regex (no-op).
- Calm inline error for invalid regex / too-few nearby words, a
no-results state, and a results-count footer.
- Nearby matches render a segmented excerpt emphasizing each matched
word and highlight every word in the book.
- BookConfig schema v2 -> v3 migrates the deprecated `matchWholeWords`
boolean to `mode` (still written for sync back-compat).
Also fix two search interactions:
- option changes (e.g. within-N-words) now take effect immediately by
reading the latest config at search time instead of a stale closure.
- closing search from the results nav bar now exits the sidebar search
mode, not just the results (search-bar visibility lifted to the store).
