Defame1297 3cd3f33706 refactor(pc-author): retrofit to the ADR-0020 context contract

Description 475 -> 213 chars, body 680 -> 212 words. Create and modify
become self-contained flow files behind a dispatch table, since the two are
mutually exclusive on whether the config already exists.

Passed its clean-context audit with no must-fix findings.

Creating a `.pre-commit-config.yaml`

Reached from SKILL.md's Route table when the repo has no config yet. Self-contained — the modify flow's file is not needed here. SKILL.md's three common gates still apply.

Steps

Detect what languages are actually in the repo with a shallow extension scan, rather than inferring them from the project's name or README:
```
git ls-files | grep -oE '\.[a-z]+$' | sort | uniq -c | sort -rn
```
Read references/hooks-by-language.md and map the detected extensions to recommended hooks. Take the repo URL, rev and args from that file rather than from memory — a rev that does not exist is the most common way a fresh config fails on its first run.

For a deliberately minimal starting point instead of a full recommendation set, pre-commit sample-config > .pre-commit-config.yaml prints a small starter config to build on.
State the proposed config in full and wait for the user's confirmation.
Write .pre-commit-config.yaml, then run pre-commit validate-config. If it exits non-zero, show the error, fix it in place, and re-validate.
