fix(github): bound historical activity backfills

[f0rr0]

Summary

• bound broad discovery to active repositories and 31-day windows, with one hard deadline covering every stage
• scope manual workers and audits to the requested account, date window, and optional repository
• continue beyond poisoned repositories and pull requests while reporting terminal evidence gaps explicitly
• keep merge artifacts as internal evidence and render each repository once per day
• add a read-only PostgreSQL audit and BDD regressions for completion, retry, gap, and projection semantics

Real-data verification

• the failed August path visited 260 accessible repositories, 21,562 refs, and 8,168 pages despite only 15 repositories being active in the window
• the corrected read-only provider traversal completed in about 13 minutes, hydrated 366 pull-request candidates with zero failures, and found 343 commit occurrences
• the current August audit correctly remains pipeline-incomplete while its stored public projection matches exactly; provider completeness is reported separately

Validation

• bun test: 239 passed
• bun run typecheck
• bun run lint
• bun run format:check
• bunx next build
