de2abaf89d refactor: streamline test suite — 33 fewer files, 11.9x faster (#670) 
* refactor: streamline test suite - cut 33 files, enable parallel execution (11.9x speedup)

Remove duplicate, low-value, and fragmented test files while preserving
all meaningful coverage. Enable parallel test execution and remove
the entire benchmark infrastructure.

Key changes:
- Consolidate workflow-validator tests (13 files -> 3)
- Consolidate config-validator tests (9 files -> 3)
- Consolidate telemetry tests (11 files -> 6)
- Merge AI validator tests (2 files -> 1)
- Remove example/demo test files, mock-testing files, and already-skipped tests
- Remove benchmark infrastructure (10 files, CI workflow, 4 npm scripts)
- Enable parallel test execution (remove singleThread: true)
- Remove retry:2 that was masking flaky tests
- Slim CI publish-results job

Results: 224 -> 191 test files, 4690 -> 4303 tests, 121K -> 106K lines
Local runtime: 319s -> 27s (11.9x speedup)

* refactor: absorb config-validator satellite tests into consolidated file

The previous commit deleted 4 config-validator satellite files. This
properly merges their unique tests into the consolidated config-validator.test.ts,
recovering 89 tests that were dropped during the bulk deletion.

Deduplicates 5 tests that existed in both the satellite files and the
security test file.

* fix: delete missed benchmark-pr.yml workflow, fix flaky session test

- Remove benchmark-pr.yml that referenced deleted benchmark:ci script
- Fix session-persistence round-trip test using timestamps closer to
  now to avoid edge cases exposed by removing retry:2

* fix: rebuild FTS5 index after database rebuild to prevent stale rowid refs

The FTS5 content-synced index could retain phantom rowid references from
previous rebuild cycles, causing 'missing row N from content table'
errors on MATCH queries.

- Add explicit FTS5 rebuild command in rebuild script after all nodes saved
- Add FTS5 rebuild in test beforeAll as defense-in-depth
- Rebuild nodes.db with consistent FTS5 index

* fix: use recent timestamps in all session persistence tests

Session round-trip tests used timestamps 5-10 minutes in the past which
could fail under CI load when combined with session timeout validation.
Use timestamps 30 seconds in the past for all valid-session test data.

* fix: regenerate package-lock.json to sync with updated dependencies

Fixes CI failure caused by package-lock.json being out of sync with
the updated n8n dependencies.

- Regenerated with npm install to ensure all dependency versions match
- Resolves "npm ci" sync errors in CI pipeline

* fix: align FTS5 tests with production boosting logic

Tests were failing because they used raw FTS5 ranking instead of the
exact-match boosting logic that production uses. Updated both test files
to replicate production search behavior from src/mcp/server.ts.

- Updated node-fts5-search.test.ts to use production boosting
- Updated database-population.test.ts to use production boosting
- Both tests now use JOIN + CASE statement for exact-match prioritization

This makes tests more accurate and less brittle to FTS5 ranking changes.

* fix: prioritize exact matches in FTS5 search with case-insensitive comparison

Root cause: SQL ORDER BY was sorting by FTS5 rank first, then CASE statement.
Since ranks are unique, the CASE boosting never applied. Additionally, the
CASE statement used case-sensitive comparison which failed to match nodes
like "Webhook" when searching for "webhook".

Changes:
- Changed ORDER BY from "rank, CASE" to "CASE, rank" in production code
- Added LOWER() for case-insensitive exact match detection
- Updated both test files to match the corrected SQL logic
- Exact matches now consistently rank first regardless of FTS5 score

Impact:
- Improves search quality by ensuring exact matches appear first
- More efficient SQL (less JavaScript sorting needed)
- Tests now accurately validate production search behavior
- Fixes 2/705 failing integration tests

Verified:
- Both tests pass locally after fix
- SQL query tested with SQLite CLI showing webhook ranks 1st

* docs: update CHANGELOG with FTS5 search fix details

Added comprehensive documentation for the FTS5 search ranking bug fix:
- Problem description with SQL examples showing wrong ORDER BY
- Root cause analysis explaining why CASE statement never applied
- Case-sensitivity issue details
- Complete fix description for production code and tests
- Impact section covering search quality, performance, and testing
- Verified search results showing exact matches ranking first

This documents the critical bug fix that ensures exact matches
appear first in search results (webhook, http, code, etc.) with
case-insensitive matching.

cfd2325ca4 fix: add FTS5 search index to prevent 69% search failure rate (v2.18.5) 
Fixes production search failures where 69% of user searches returned zero
results for critical nodes (webhook, merge, split batch) despite nodes
existing in database.

Root Cause:
- schema.sql missing nodes_fts FTS5 virtual table
- No validation to detect empty database or missing FTS5
- rebuild.ts used schema without search index
- Result: 9 of 13 searches failed in production

Changes:
1. Schema Updates (src/database/schema.sql):
   - Added nodes_fts FTS5 virtual table with full-text indexing
   - Added INSERT/UPDATE/DELETE triggers for auto-sync
   - Indexes: node_type, display_name, description, documentation, operations

2. Database Validation (src/scripts/rebuild.ts):
   - Added empty database detection (fails if zero nodes)
   - Added FTS5 existence and synchronization validation
   - Added searchability tests for critical nodes
   - Added minimum node count check (500+)

3. Runtime Health Checks (src/mcp/server.ts):
   - Database health validation on first access
   - Detects empty database with clear error
   - Detects missing FTS5 with actionable warning

4. Test Suite (53 new tests):
   - tests/integration/database/node-fts5-search.test.ts (14 tests)
   - tests/integration/database/empty-database.test.ts (14 tests)
   - tests/integration/ci/database-population.test.ts (25 tests)

5. Database Rebuild:
   - data/nodes.db rebuilt with FTS5 index
   - 535 nodes fully synchronized with FTS5

Impact:
- ✅ All critical searches now work (webhook, merge, split, code, http)
- ✅ FTS5 provides fast ranked search (< 100ms)
- ✅ Clear error messages if database empty
- ✅ CI validates committed database integrity
- ✅ Runtime health checks detect issues immediately

Performance:
- FTS5 search: < 100ms for typical queries
- LIKE fallback: < 500ms (unchanged, still functional)

Testing: LIKE search investigation revealed it was perfectly functional,
only failed because database was empty. No changes needed.
