fix: synchronize ignore baselines across CodeRabbit and Augment configs

Expand path exclusions in both PR review tools to a shared baseline:
- Mutual config exclusions (each tool ignores its own and others configs)
- Build output, vendored/generated files, package metadata, binary/media
- Test fixtures, non-project dirs, AI assistant dirs, build temp
- Generated reports

CodeRabbit goes from 1 exclusion to 32; Augment from 12 to 32.
ESLint already had comprehensive ignores and is unchanged.

Addresses CodeRabbit findings F2 and F4 from PR bmad-code-org#1511 review.
