Hakkutsu 2.6.3

• Speed up subtitle loading with staggered fallback transports and cancellation when tracks change.
• Share playback timing, remove full-track scans in subtitle gaps, reduce redundant rendering, and prioritize current-cue readings over off-screen transcript work.
• Cache repeated reading/translation requests, skip unnecessary kana dictionary requests, and show subtitle tokens before enrichment finishes.
• Calculate immersion difficulty from vocabulary in the main reading content, with separate script density, JLPT coverage, and mature/learning SRS statistics.
• Add an attributed offline JLPT vocabulary index and complete Unicode-based Hán-Việt fallbacks, including repairs for incomplete saved compounds.
• Improve selective furigana, dictionary import validation, popup startup, and the styling of page difficulty and offline dictionary controls.
• Add unit tests, browser fixtures, performance benchmarks, and packaged third-party notices.

Validation: 32 unit tests, TypeScript, and Chrome/Firefox production builds. The underlying changes also passed 23 local browser scenarios; details and limits are recorded in tests/SUBTITLE-PERFORMANCE.md and tests/DENSITY-RESULTS.md.
