Automated release: version and notes generated from pull requests merged since 3.8.6.

Fixed

• What the tools and the contract say, made to match what they do (#466: A193, A194, A195,
  A198, A202; #467 A226; #464 A122; #463 A155). graphics.py --dry-run on an input an earlier
  step would write refused "--end must be after --start" (the probe stub's 0 s read as the
  clip's end); with no --end it now plans to a placeholder 10 s after --start and says so in
  notes (silence, crop, freeze, loop, redact, speedramp and multicam still refuse
  a dry run on such an input). contract --json: probe is analysis_only under --dry-run,
  since --analyze decodes with ffmpeg; output_schema gains the top-level keys these tools emit
  and it left out: cropdetect (crop, confidence, file, source_width, source_height,
  motion_centre), probe (levels, audio_streams, stream_counts and others), graphics, join,
  loudness, multicam, broll, grid, scenes, batch, render and report, and join's mode enum gains
  copy (a test runs those tools and fails on an emitted key the schema lacks); every tool description is the docstring's first sentence,
  where 16 ended mid-phrase on the first physical line; error_kinds names the encoders, the
  VP9 decoder and the speech engines under missing_tool, and loudness.py, join.py --copy
  and render.py's social pack under verification; color.py's alpha_codec description says a
  10- or 12-bit ProRes 4444 alpha keeps 8 bits of precision through --correct/--lut. An
  FFmpeg older than 6.1 is refused with a hint that names a newer build, not sudo apt install ffmpeg, which reinstalls the same version. export.py --normalize's help lists the platform
  presets it takes from the table (10), not four.
• Docs that disagreed with the code (#466: A191, A192, A197, A199, A200, A201, A209, A210,
  and references/flags.md's dry-run list; #467 A32; #463 A155). SKILL.md's slow-motion row
  (fit.py --duration 2x) and blank-clip row (background.py without --width/--height)
  failed on every input. docs/contract.md's role and verification-policy tables cover all 42
  tools, and requires_visual_verification is stated as the tools whose row names look; a test
  compares both tables with the contract. references/workflow.md and gotchas.md no longer say
  scenes refuses audio, or prescribe --lang for overlay.py, which has none.
  ci-platform-pitfalls.md's drawtext remedy names the flag each tool has. flags.md states
  verify.py's 600 s per-step --timeout, the tools without -o, and the whole dry-run list.
  README: the fake-ffmpeg dry-run test now has a case for every tool whose dry run runs no ffmpeg
  (it had 19 cases over 18 tools), the Windows skips are described without a count, and a push
  with nothing to release still asks the MCP Registry (release.yml's comment says the same).
  docs/design-decisions.md: color.py's merged alpha is 8-bit, not "kept as decoded".
