Fixes VersionedNodeType parsing failures where test mocks only have
baseDescription without the description getter that real instances have.
Changes:
- Add baseDescription fallback in regular (non-VersionedNodeType) paths
- Check instance-level baseDescription/nodeVersions for versioned detection
- Prevent fallback for incomplete mocks testing edge cases
This resolves 11 test failures caused by v2.17.5 TypeScript type safety
changes interacting with test mocks that don't fully implement n8n's
VersionedNodeType interface.

Added comprehensive TypeScript type definitions for n8n node parsing while
maintaining zero compilation errors. Uses pragmatic "70% benefit with 0%
breakage" approach with strategic `any` assertions.
## Type Definitions (src/types/node-types.ts)
- NodeClass union type replaces `any` in method signatures
- Type guards: isVersionedNodeInstance(), isVersionedNodeClass()
- Utility functions for safe node handling
## Parser Updates
- node-parser.ts: All methods use NodeClass (15+ methods)
- simple-parser.ts: Strongly typed method signatures
- property-extractor.ts: Typed extraction methods
- 30+ method signatures improved
## Strategic Pattern
- Strong types in public method signatures (caller type safety)
- Strategic `as any` assertions for internal union type access
- Pattern: const desc = description as any; // Access union properties
## Benefits
- Better IDE support and auto-complete
- Compile-time safety at call sites
- Type-based documentation
- Zero compilation errors
- Bug prevention (would have caught v2.17.4 baseDescription issue)
## Test Updates
- All test files updated with `as any` for mock objects
- Zero compilation errors maintained
## Known Limitations
- ~70% type coverage (signatures typed, internal logic uses assertions)
- Union types (INodeTypeBaseDescription vs INodeTypeDescription) not fully resolved
- Future work: Conditional types or overloads for 100% type safety

Updated trigger detection logic in both parsers to check if a node's group array includes 'trigger'. This fixes an issue where webhook, cron, interval, and emailReadImap nodes were not being identified as triggers despite having category='trigger'.
Note: After pulling this change, run `npm run rebuild` to update your local database.
