Evidence: lint, format and type check (issue-188)

The same commands CI runs (make lint format-check typecheck validate), from the project root.

make lint — ruff + markdownlint over every markdown file

$ 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: 501 file(s)
Summary: 0 error(s)

make format-check — CI parity with pre-commit's ruff format

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

make typecheck

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

make validate — the config files against their schemas

$ make validate
uv run python scripts/validate_config.py
