v0.7.0

Changed

• Timecode citations are now parsed, not pattern-matched. export_web.py used a
  single "one label + one time" regex, so every other way a writer naturally cites a
  moment fell through as dead plain text — with no error anywhere, because a
  non-match is indistinguishable from prose. Worse, the bullet's data-time-source
  silently degraded to inherited, meaning it reused the previous bullet's
  timestamp for scroll-sync. An audit of 79 delivered courses found 51 affected,
  8,086 citations, and 7,118 of 27,177 timed bullets (26%) mis-positioned.
  The parser now accepts:
  • ranges — (V1 04:22–04:31) → one pill showing the range, jumping to its start
  • lists — (V1 05:02, 06:13) → one jumpable pill per time
  • cross-clip spans — (clipA 29:50–clipB 01:25) → each end keeps its own pill
  • three-digit minutes (V1 100:43) and second-only range ends (V2 28:30-42)
  • a leading note — (practice V1 00:09), (c00 14:17) — kept verbatim
  • labels declared by the note's own ## 影片代號 table, so an audio-only source
    cited as (A1 06:59) resolves; this table now outranks the positional V-map,
    which was wrong for notes that continue numbering across segments
  • an unlabelled (08:27–12:33) only when the segment has exactly one media
    file. With more than one candidate it stays plain text: a pill pointing at the
    wrong video is worse than no pill.
    Seconds are validated as 00–59 so prose like (120:80) cannot match.

Fixed

• A citation naming a file the course does not have no longer becomes a link.
  One MEDIA_REL check now gates every route that produces a filename (V-map,
  declared table, literal citation, single-clip fallback), so a parsing slip
  downgrades to plain text instead of minting a button that silently does nothing.
• Filenames containing a comma resolve. A real clip may be named
  20221029_143246-ACL, PCL, menisc, TFCC.mp4; the grammar would have read those
  commas as a list of times. A fast path matches the whole parenthesised run against
  the manifest before the general grammar runs.
• Placeholder names in two docstrings replaced with <speaker>/<topic>.
