Static analysis — lint, format, types, config (issue-274)

Every check clean on its first run after the change. Same tools CI runs (make lint, make format-check, pyright, scripts/validate_config.py — the pre-commit set).

make lint

$ uv run ruff check cli hooks
All checks passed!
$ npx --yes markdownlint-cli2@0.18.1 "**/*.md"
markdownlint-cli2 v0.18.1 (markdownlint v0.38.0)
Linting: 850 file(s)
Summary: 0 error(s)

Run on the rebased tree (main at 71e7dff): 850 markdown files — 841 on the branch before the rebase, plus issue-273's, which landed in between.

make format-check

$ uv run ruff format --check cli hooks
250 files already formatted

Types

$ uv run pyright cli
0 errors, 0 warnings, 0 informations

Config schema validation
