v0.0.9.post1 — Docs, tests & CI sync

Summary

Maintenance release that aligns the documentation, test suite, and GitHub Actions pipelines with the current state of the v0.0.9 codebase. No runtime/API behavior changes versus v0.0.9.

What's Changed

Documentation

• Root CLAUDE.md and tests/CLAUDE.md brought back in sync with the actual subpackage layout, env vars, and CLI entry points (proxbox-proxmox-codegen, proxbox-schema).
• New env var documentation: PROXBOX_BULK_BATCH_SIZE, PROXBOX_BULK_BATCH_DELAY_MS, PROXBOX_GENERATED_DIR.
• MkDocs reference updated:
  • GET /cache/metrics and GET /cache/metrics/prometheus added to the HTTP reference.
  • overwrite_* and sync_vm_network query params documented on VM stream endpoints.
  • Tag-preservation behavior added to the VM sync workflow.
  • Phantom benchmark block in the caching architecture page replaced with the real cache-metrics endpoints.
• pt-BR mirror pages added as stubs (with a "Tradução pendente" admonition + EN body) so mkdocs build --strict is green: sync/overwrite-flags.md, development/refactoring-summary.md, development/sync-fix-summary.md.

Tests

• New focused suites:
  • tests/test_auth_lockout.py — 9 tests covering the full proxbox_api/auth.py lockout state machine (valid key, missing key, no keys configured, attempt counting, lockout-on-cap, success-clears-attempts, lockout expiry, persistence across sessions, async path).
  • tests/test_schema_cli.py — 8 tests for the argparse-based proxbox-schema CLI (list/status/generate, --force, pipeline failure exit code).
• Removed the dead image_http pytest marker (plus its CI filter and shell-script reference); the test it referenced no longer exists.
• tests/CLAUDE.md test inventory replaced with the current 47-file layout; e2e description corrected (httpx, not Playwright).

GitHub Actions / CI

• Fixed non-existent action pins (upload-artifact@v7, download-artifact@v8 → @v4) in nightly-schema-refresh.yml and publish-testpypi.yml.
• Aligned ty check scope across ci.yml, nightly-schema-refresh.yml, docker-hub-publish.yml, publish-testpypi.yml, and .pre-commit-config.yaml to include proxbox_api/schemas/sync.py.
• nightly-schema-refresh.yml now installs the playwright extra it actually needs.
• New test-py311-floor job in ci.yml exercises the declared requires-python = ">=3.11" floor (heavy E2E matrix stays on 3.12).
• Removed dead PROXBOX_E2E_NETBOX_TOKEN_VERSION env var.

Style

• proxbox_api/app/full_update.py and proxbox_api/session/netbox.py reformatted with ruff format to clear pre-existing format drift that was blocking CI.

Compatibility

• Python ≥ 3.11 (3.11 floor is now actually exercised in CI)
• NetBox v4.6.0-beta2 schema certification carried over from v0.0.9
• proxmox-sdk == 0.0.3.post1, netbox-sdk == 0.0.7.post6 (unchanged)
