Summary by CodeRabbit
New Features
Added speech-based reading progress tracking that matches spoken text to the script, tolerates minor recognition differences, and supports one-word rewind and repetition resets.
Added Korean text normalization for matching, including handling of punctuation, spacing, Hangul, and numbers.
Progress can follow partial and final speech recognition results, avoid moving backward during matching, and recover when recognition text does not align.
This change adds pure Dart logic to normalize text, tokenize scripts, match transcript hypotheses to script positions, and track reading progress across partial and final transcripts.

Summary
Text normalization and script tokenization lib/src/features/reading/domain/text_normalizer.dart, lib/src/features/reading/domain/script_tokenizer.dart, test/features/reading/domain/text_normalizer_test.dart, test/features/reading/domain/script_tokenizer_test.dart
TextNormalizer creates comparison units, including Korean number readings and decomposed Hangul. ScriptTokenizer stores retained tokens with their original text and UTF-16 offsets. Tests cover normalization, token indices, and source ranges.
CursorMatcher evaluates candidate positions from the anchor through a configured skip limit. It selects token boundaries by normalized edit distance and returns a match only when the distance meets the policy limit. Tests cover boundaries, recognition differences, repeated words, and skip handling.
ReadingProgress accumulates final transcript text and matches partial results against pending text. Transcript matching does not move the cursor backward. The class also handles one-word rewind, transcript segment resets, repetition resets, and completion updates. Tests cover these state changes.

Merge Risk: Moderate · previous review f96ac
A shorter final transcript can prevent later confirmation of intervening words. Keep the anchor at the last confirmed boundary before merging.

Make anchor and cursor read-only outside ReadingProgress.
The repository contract allows speech recognition to move progress forward and only explicit rewind to decrease it. These public fields let a caller bypass that contract and change state without synchronizing _pendingFinalText or the other cursor state. No current caller writes them, so this is an API invariant gap rather than a demonstrated workflow failure.

`_anchor` is set from the confirmed `match.cursor`, not the farther `_cursor`;
when discarding unmatched pending text at the limit, leave `_anchor` unchanged.
Keep the anchor at the last confirmed boundary.
