v0.19.0 — TUI parity for the screenrecording iteration loop

0.19.0 — TUI parity for the screenrecording iteration loop

No migration.

The TUI can now originate the full video loop from 0.18.0 — import a
screen recording, upload it with the iteration-plan template, and browse
the resulting cue frames — plus small API/CLI surface completions.

Added

• Video import in the TUI record screen. The Import picker (ctrl+u)
  accepts .mp4/.mov alongside audio: the flat recordings list
  includes video (marked 🎬), the browse-mode directory tree filters to
  the full accepted set, and the picker hints/docs name every extension.
• Iteration-plan toggle. New sticky "Iter. plan" toggle in the
  record screen's toggles row (default ON, persisted). Video uploads
  send summary_template=iteration-plan; audio uploads are unaffected
  (a plan keyed to cue frames makes no sense for a meeting).
• vezir scribe --template — run_scribe accepts and forwards
  summary_template, mirroring summary_preset; every upload path
  (CLI, scribe, TUI, API) now has template parity.
• Retry-summary with template from the TUI. The detail screen's
  preset picker gains a template field (prefilled with the session's own
  template, or iteration-plan for video sessions that lack one);
  VezirClient.retry_summary(template=) sends it (server >= 0.18.0).
• Video + template visibility. Session keeps the server's video
  and summary_template fields (new is_video): video sessions show a
  · 🎬 badge in the sessions list and 🎬 video / template: lines in
  the detail meta block.
• Cue-frame grouping. cue_*.png attachments (up to 45 on a video
  session) collapse into a single "N cue frames" row in the artifacts
  table; Enter opens a frame-list modal, and each frame opens through
  the existing attachment viewer (OS image viewer). All other
  attachments keep their own rows. Inline image preview stays deferred.

Tests

• 1121 passing (was 1110 at 0.18.0). New: video scan/label/picker tests,
  _template_for rules, record-body upload kwargs, preset-picker
  3-tuple + template roundtrip, retry-summary template body,
  Session.from_dict video/template fields, detail-screen badges +
  frame grouping incl. the FrameListScreen → ArtifactScreen chain.
