test: massive test coverage expansion (+1,437 tests, 22 new files)
Expand test coverage across all layers via 14 parallel agents: Unit tests (3,378 total, +534): - First-ever AI sidecar tests (157 tests covering bridge lifecycle, all 12 tool modules) - API route infrastructure (auth, pipeline, batch, settings, teams, roles, audit, api-keys, files, docs) - Lib coverage improvements (audit 7%->95%, worker-pool 33%->100%) - Web store/lib gap fills (features-store, tool-registry) Integration tests (4,403 total, +903): - Expanded 19 tool test files with parameter variations, format edge cases, boundary values - Cross-format matrix: 290 tests covering 14 tools x 17 formats - Adversarial/edge cases: 63 tests for extreme inputs, concurrent requests, corrupted files E2E-Docker (125 new tests): - Expanded 8 spec files + 1 new file covering all 49 tools - Added HEIC/format handling, auth failures, download verification GUI E2E (expanded 28 spec files): - Navigation, responsive layout, keyboard shortcuts - All 51 tool UIs with settings, processing, display modes - Batch/pipeline workflows, settings/RBAC, visual regression - Resilience, accessibility (ARIA, contrast, focus), performance budgets
