The union candidate fetch wrapped both listWorkPackages() legs in an
unconditional .catch(() => ({ items: [] })), swallowing 401/403/429 and
OpenProjectAuthenticationError along with genuinely transient failures. An
expired token would silently degrade to "0 candidates", and the LLM would
report work packages as not found rather than surfacing the auth failure.
Replace the inline catches with a shared listCandidates() helper that uses
isFatalSearchError (already used by searchPipeline) to rethrow fatal errors
and only swallow non-fatal ones, preserving the property that a bad response
on one leg doesn't kill the other leg's candidates.

Registers openproject_search_work_packages (readOnly: true), taking the tool
registry from 18 to 19. searchWorkPackages now unions a precise server-side
subject filter with a broad recency-ordered candidate window, ranks via the
shared search pipeline, and deep-enriches top candidates with description and
comment text. Exact-mode requests skip the broad query entirely.
searchWorkPackages's return type changes from a flat PaginatedResult<WorkPackageSummary>
to WorkPackageSearchPage, nesting the summary under `workPackage` alongside
score, matchedFields, and an optional snippet.
