chore: small polish — untrack .coverage, sister cross-links, author signature (#1)

- Remove .coverage (86 KB binary Python coverage data) from tracking; add
  .coverage and htmlcov/ to .gitignore. The file should never have been
  committed.
- Add "Related — Claude Code ecosystem by the same author" section to
  both README.md and README.ru.md, cross-linking to all 8 sister repos
  (anti-regression-setup, ai-context-hierarchy, claude-statusline,
  notebooklm-claude-workflows, lingua-companion, security-scanner,
  diabot, ghost-showcase). Consistent with footer pattern across all
  sister-repo READMEs.
- Add Author signature to footer (Nick Podolyak with GitHub / Habr /
  dev.to / Telegram links). Was missing — every sister repo has it.

This is small additive polish on a repo that was already at a high
standard (CI matrix Linux/macOS/Windows, npm package, 20 topics, 113
tests, bilingual EN/RU, mermaid arch, 7 hero badges, public-beta status).
