refactor: remove audit bloat

[vnedyalk0v]

Summary

Removes over-engineered or premature Codeflow surface from the repository:

• deletes the future /flow-report schema, prompt, and template scaffold until that command exists
• stops guidance, lifecycle docs, and config from advertising unregistered workflow commands as expected tools
• replaces repeated JSON schema validation and JSON payload file readers with shared helpers
• reuses one GitHub review-thread GraphQL mutation response parser for reply and resolution clients
• deletes pointer-only examples docs and an unused git branch re-export

Impact

This keeps the current command surface focused on implemented commands: /flow-start, /flow-check, /flow-commit, /flow-pr, /flow-watch, /flow-comments, and /flow-fix-comments.

Existing final response expectations remain documented as agent/reporting behavior, not as a non-existent /flow-report tool.

Verification

• npx tsc --noEmit
• npx vitest run tests/guidance/build-guidance.test.ts tests/lifecycle/lifecycle-transitions.test.ts tests/schemas/payload-schemas.test.ts tests/commands/flow-start.test.ts tests/commands/flow-commit.test.ts tests/commands/flow-pr.test.ts tests/commands/flow-comments.test.ts tests/commands/flow-fix-comments.test.ts tests/github/pr-review-thread-replies-client.test.ts tests/github/pr-review-thread-resolution-client.test.ts
• npm run check
• git diff --check
• post-commit npm run check

Self-review

• Confirmed the only remaining /flow-report and unregistered command references are negative regression assertions or prompt filenames, not advertised tool guidance.
• Confirmed deleted artifacts are covered by schema tests.
• Confirmed the full package gate passes after commit.
