chore: pre-commit clean run — ruff-format, markdownlint, mypy 1.11

Wired all hooks into a clean run that contributors can rely on:

- ruff-format: applied formatting across 46 .py files (single-line
  collapses, parameter wrapping). No behavior changes.
- markdownlint: auto-fix swept blank-line and end-of-file issues
  across 14 doc files. Manual fixes: 5 fenced blocks gained `text`
  language (tree diagrams + plain output), 2 long lines wrapped,
  MD029 disabled in config because the walkthroughs use explicit
  step numbers across code-block separators.
- detect-private-key: excluded .env-example (placeholder PGP block
  header was flagging on its `-----BEGIN ...-----` marker).
- mypy 1.11 (the pre-commit pin) flagged `Returning Any` on
  keyring.get_password; added an explicit `str | None` binding.
  Local mypy 2.1.0 didn't catch it but consistency wins.
- ruff PT004: clean_env fixture in conftest.py is setup-only and
  intentionally named without an underscore (it's visible at test
  call sites as a setup marker); silenced for that one file.
- Scoped pre-commit mypy to `src/` to match CI invocation; was
  reaching into `tests/` with --strict and surfacing untyped test
  helpers that CI doesn't gate.
