Add Advance Auto Parts and speed Workday pagination

[viktor-shcherb]

Summary

• add Advance Auto Parts with its centralized Workday board, localized descriptions, metadata, and verified logo/icon assets
• paginate capped Workday facet partitions with bounded concurrency
• share the query semaphore across multi-site runs so tenant-level request concurrency remains bounded
• add regression coverage for concurrent facet pagination

Guided-workflow evidence

The validated inventory seed matched the official Advance Auto Parts tenant. The normal probe reported 16,495 live jobs, consistent with the issue's 16,420-job inventory estimate. A full ws run monitor reached Workday's 2,000-result cap, split into 55 location facets, and was terminated before completion because those facet partitions were paginated sequentially.

Official careers research found one centralized board covering the company's regions and employing entities; localized Phenom pages are presentation mirrors of the same Workday source.

Root cause and fix

Large Workday boards require hundreds of 20-item list requests after facet splitting. The monitor streamed results per facet but awaited each complete facet serially. This change runs facet partitions concurrently behind a five-query semaphore and shares that bound across multi-site discovery. Outstanding tasks are cancelled cleanly if the global job cap is reached or the generator exits.

Validation

• uv run pytest tests/test_workday.py — 78 passed
• uv run ruff check src/core/monitors/workday.py tests/test_workday.py
• uv run ws validate
• live Advance Auto Parts monitor — 16,517 jobs, 111.7s, untruncated

Closes #6368

Maintainer review resolution:

• Rebased onto current main; the Workday runtime changes are no longer duplicated here because Support nested Workday facets for TJX #6433 now provides the stricter shared implementation (nested facets, 100-value request bounds, shared five-query concurrency, direct-pagination fallback, and unique-inventory completeness checks).
• Reused the cleaner already-uploaded cropped wordmark and icon; removed duplicate raw assets from this branch.
• Verified company identity/metadata and corrected the canonical website and ticker/Wikidata links.
• Fresh bounded detail sample: 10/10 clean titles and substantive descriptions (4.2–9.2 KB), 10/10 employment types and posting dates, 9/10 full-address locations. One current posting exposes only store identifier 6069; the raw Workday detail API has no richer location, so that is an upstream limitation.
• The original full run enumerated 16,517 untruncated jobs. A repeat full run today stalled in five tenant-side requests for over 80 minutes and was stopped; it was not counted as a successful validation.
• ws validate, 88 Workday tests, and Ruff pass. Version is 0.13.289.
