Adds caption-qa, a skill for checking SRT and WebVTT captions against published caption standards and fixing what fails. None of the current skills covers captions or subtitles.

Why it's more than the model's defaults: each standard sets different numbers, and models don't reliably know them or measure them consistently. The skill:

• gives a limits table for Netflix English (adult and children's), the BBC subtitle guidelines and the DCMP Captioning Key, linked to each source page;
• states the counting rules: characters per second, words per minute, frame-based gaps at the video's frame rate, overlaps;
• sets a fix order that retimes before it rewords, so captions stay verbatim.

It also includes a short, self-contained Python check that applies those limits and exits with 1 on failure, for CI. No external tools or packages. It gives the same result as an existing caption checker on a sample file (2 of 8 captions pass, the same six failures).

Checks run locally:

• npm run skill:validate
• npm start (adds the README row)
• npx @microsoft/vally-cli lint skills/caption-qa: 2 of 2 checks passed
• codespell

I re-read the BBC and DCMP limits on their pages today. The Netflix numbers come from its English (USA) style guide and timing guidelines.

Drafted with AI assistance. Every limit was checked against its source page, and the script was tested on SRT and WebVTT samples.

Thanks @markksantos. This is well sourced, and the per-standard limits table plus the retime-before-reword order are the kind of specifics that help over model defaults.
