chore(cleanup): J1 — purge 220MB of debris, archive session docs

Remove accidentally-committed artifacts from v1.0.3 → v1.0.4 cleanup sprint:

Binaries (5, ~167 MB):
- veza-backend-api/{server,modern-server,encrypt_oauth_tokens,seed,seed-v2}

Reports & logs (frontend):
- 9 lint_report*.json (~32 MB)
- tsc_*.{log,txt}, ts_*.log (TypeScript error snapshots)
- storybook_*.json (1375+ stored errors)
- build_errors*.txt, final_errors.txt, build_output.txt

Reports & logs (backend):
- coverage*.out + coverage_groups/ (70 files, ~4 MB)
- 3 internal/handlers/*.go.bak files

Root audit screenshots:
- 54 audit-*.png (~11 MB visual regression baselines)

Session docs archived (not deleted):
- 78 apps/web/*.md → docs/archive/frontend-sessions-2026/
- 43 veza-backend-api/*.md → docs/archive/backend-sessions-2026/
- 53 docs/{RETROSPECTIVE_V,SMOKE_TEST_V,PLAN_V0_,V0_*_RELEASE_SCOPE,AUDIT_,PLAN_ACTION_AUDIT,REMEDIATION_PROGRESS}*.md → docs/archive/v0-history/

Stale scripts removed (Jan 2026 MVP-era, hardcoded v0.101):
- start_{iteration,mvp,recovery}.sh
- test_{mvp_endpoints,protected_endpoints,user_journey}.sh
- validate_v0101.sh, verify_logs_setup.sh, gen_hash.py

.gitignore updated to prevent recurrence.

README.md and CONTRIBUTING.md preserved in both apps/web/ and veza-backend-api/.

Total: 169 deletions, 174 renames, 1 .gitignore modification.
