fix: resolve critical complexity routing issues from multi-agent review
Fixes 6 critical issues discovered in multi-agent code review:
1. **Parameter propagation** - CRITICAL FIX
- Added complexity_level parameter to super-dev-pipeline invocations
- Fixed both sequential and parallel execution paths
- Without this, complexity routing was completely non-functional
2. **Keyword matching rules** - CRITICAL FIX
- Defined explicit matching algorithm in workflow.yaml
- Case insensitive, word boundary matching, exact strategy
- Added keyword variants (auth -> authentication, authorize, etc.)
- Scan locations: story_title, task_descriptions, subtask_descriptions
3. **Threshold decision tree** - CRITICAL FIX
- Rewrote overlapping logic to be mutually exclusive
- Priority order: COMPLEX → MICRO → STANDARD
- Prevents stories from matching multiple categories
4. **Task counting method** - CRITICAL FIX
- Defined method: "top_level_only" (ignore subtasks)
- Added documentation with examples
- Eliminates ambiguity in complexity scoring
5. **max_files implementation** - FIX
- Added file_count ≤ 5 check to MICRO classification
- Previously extracted but never used (dead code)
6. **Version synchronization** - FIX
- Updated super-dev-pipeline to v1.3.0 (was 1.2.0)
- Matches batch-super-dev version for consistency
Impact: These fixes make complexity routing actually functional. The original
implementation computed complexity but never passed it to the pipeline,
rendering the entire feature non-operational.
