* fix(gsd): migrate completion/validation prompts to DB-backed tools and fix pipeline inconsistencies (#2444)
- Create gsd_validate_milestone tool (handler + DB registration) using assessments table
- Update complete-milestone.md to use gsd_complete_milestone instead of manual file writes
- Update validate-milestone.md to use gsd_validate_milestone + gsd_reassess_roadmap for remediation
- Add buildSkillActivationBlock() to 4 missing prompt builders (complete-milestone, validate-milestone, run-uat, reassess-roadmap)
- Remove dead completedSliceSummaryPath variable from reassess-roadmap builder
- Remove dead "degraded fallback" sections from replan-slice.md and reassess-roadmap.md
- Fix plan-slice.md double-tool instruction (gsd_plan_slice already persists tasks)
- Fix inconsistent commit/write instructions in complete-milestone.md

* fix: update tests for new tool registration and prompt changes
- Add gsd_validate_milestone to tool-naming RENAME_MAP (24→26 tools)
- Update prompt-contracts assertions for removed fallback text and singular DB tool phrasing
- Restore {{roadmapPath}}, {{assessmentPath}}, {{planPath}}, {{replanPath}} template vars in prompts for context

* fix: restore {{milestoneSummaryPath}} template var in complete-milestone prompt
Test expects the milestone summary path reference in the prompt content.
