feat: Generate implementation tasks for unified workflow

- Created 28 tasks across 5 phases (Setup, Tests, Core, Integration, Polish)
- Phase 3.2: 6 test tasks covering CI-only, CI+Release, and manual trigger modes
- Phase 3.3: 6 core tasks for conditional execution logic in workflow.yml
- Phase 3.4: 6 integration tasks for deprecation and file removal
- Phase 3.5: 7 polish tasks for documentation and validation
- Marked 15 tasks as parallel [P] (different files, no dependencies)
- Sequential tasks for workflow.yml modifications (T010-T015)
- All test tasks before implementation (TDD red-green-refactor)
- Added validation checklist (all items passed)
- Updated PR #199 description with task checkboxes

+# Tasks: Unified CI and Release Workflow
+
+**Input**: Design documents from `/specs/001-merge-ci-release-workflows/`
+**Prerequisites**: plan.md (required), research.md, data-model.md, contracts/
+
+## Execution Flow (main)
+
+1. Load plan.md from feature directory
+   → Extract: GitHub Actions YAML, PowerShell 7.4+, reusable workflow structure
+2. Load optional design documents:
+   → data-model.md: Extract TriggerContext, JobExecutionPlan entities
+   → contracts/workflow-api.md: Extract workflow inputs, secrets, conditional logic
+   → research.md: Extract decisions on conditional execution, authentication
+   → quickstart.md: Extract migration scenarios
+3. Generate tasks by category:
+   → Setup: Repository structure validation, deprecation notices
+   → Tests: Workflow validation tests for CI-only and CI+Release modes
+   → Core: Conditional job execution logic in workflow.yml
+   → Integration: Deprecation of CI.yml, removal of separate publish workflows
+   → Polish: Documentation updates, migration guide validation
+4. Apply task rules:
+   → Different workflow files = mark [P] for parallel
+   → Same workflow file = sequential (no [P])
+   → Tests before implementation (TDD)
+5. Number tasks sequentially (T001, T002...)
+6. Generate dependency graph
+7. Create parallel execution examples
+8. Validate task completeness:
+   → Workflow API contract validated?
+   → Both execution modes tested?
+   → Migration paths documented?
+9. Return: SUCCESS (tasks ready for execution)

+## Format: `[ID] [P?] Description`
+
+- **[P]**: Can run in parallel (different files, no dependencies)

+
+## Dependencies
+
+### Phase Dependencies
+- Setup (T001-T003) before all other phases
+- Tests (T004-T009) before Core implementation (T010-T015)
+- Core (T010-T015) before Integration (T016-T021)
+- Integration (T016-T021) before Polish (T022-T028)
+
+### Specific Task Dependencies
+- T004, T005, T006 must fail before T010, T011 implemented
+- T007, T008 depend on T004, T005, T006 being written
+- T010 blocks T016, T017, T018 (workflow.yml must have publish logic before removing separate files)
+- T015 depends on T010, T011, T012, T013, T014 (all workflow changes complete)
+- T021 depends on T010-T015 (v5 workflow ready)
+- T022 depends on T016-T021 (migration scenarios finalized)
+- T026 depends on T022 (migration guide complete)

+## Parallel Execution Examples
+
+### Phase 3.2: Tests (All Parallel)
+```plaintext
+# Launch all test creation tasks together:
+Task: "Create test workflow for CI-only mode (unmerged PR) in .github/workflows/Test-Workflow-CI-Only.yml"
+Task: "Create test workflow for CI+Release mode (merged PR) in .github/workflows/Test-Workflow-Release.yml"
+Task: "Create test workflow for manual trigger behavior in .github/workflows/Test-Workflow-Manual.yml"
+Task: "Update .github/workflows/Workflow-Test-Default.yml to test unified workflow"
+Task: "Update .github/workflows/Workflow-Test-WithManifest.yml to test unified workflow"
+```
+
+### Phase 3.4: Integration (File Removals/Deprecations Parallel)
+```plaintext
+# Launch deprecation tasks together (different files):
+Task: "Remove .github/workflows/Publish-Module.yml (logic now in workflow.yml)"
+Task: "Remove .github/workflows/Publish-Site.yml (logic now in workflow.yml)"
+Task: "Mark .github/workflows/Workflow-Test-Default-CI.yml as deprecated"
+Task: "Mark .github/workflows/Workflow-Test-WithManifest-CI.yml as deprecated"
+```
+
+### Phase 3.5: Polish (Documentation Parallel)
+```plaintext
+# Launch documentation tasks together:
+Task: "Create migration guide docs/migration/v5-unified-workflow.md with all three scenarios"
+Task: "Update README.md with unified workflow documentation and breaking change notice"
+Task: "Update .github/copilot-instructions.md with unified workflow as active technology"
+Task: "Create manual test checklist docs/migration/manual-testing.md for consuming repositories"
+Task: "Add CHANGELOG.md entry for v5.0.0 breaking change"
+```
+
+## Notes
+
+- **[P] tasks** = different files, no dependencies, safe to run in parallel
+- **Sequential tasks** (no [P]) = modify same file (.github/workflows/workflow.yml) and must run in order
+- Verify all test workflows FAIL before implementing conditional logic (TDD Red phase)
+- Commit after each task to enable rollback if needed
+- Test workflow execution locally where possible using `act` or GitHub CLI
+- Avoid: modifying workflow.yml in multiple parallel tasks (sequential T010-T015)
+
+## Task Generation Rules
+
+*Applied during main() execution*
+
+1. **From Contracts** (workflow-api.md):
+   - Workflow API contract → test workflow validation tasks [P]
+   - Conditional execution logic → implementation tasks (sequential, same file)
+   - Input/output compatibility → validation test tasks [P]
+
+2. **From Data Model** (data-model.md):
+   - TriggerContext entity → conditional logic implementation tasks
+   - CI-Only execution mode → test workflow task
+   - CI+Release execution mode → test workflow task
+   - JobExecutionPlan → job dependency validation task
+
+3. **From Research** (research.md):
+   - Publishing target decision → Publish-Module job update task
+   - Versioning strategy → version reference update tasks
+   - Manual trigger behavior → manual trigger test task
+   - Authentication → secrets validation task
+
+4. **From Quickstart** (quickstart.md):
+   - Migration Scenario 1 → documentation task
+   - Migration Scenario 2 → documentation task
+   - Migration Scenario 3 → documentation task
+   - Manual testing steps → manual validation task
+
+5. **Ordering**:
+   - Setup → Tests → Core (workflow.yml mods) → Integration (file removals) → Polish (docs)
+   - All tests before implementation (strict TDD)
+   - Sequential tasks within workflow.yml (T010-T015)
+   - Parallel tasks for different files (tests, docs, deprecations)
+
+## Validation Checklist
+
+*GATE: Checked by main() before returning*
+
+- [x] All contracts have corresponding tests (workflow-api.md → T004-T008)
+- [x] All entities have tasks (TriggerContext → T010, JobExecutionPlan → T015)
+- [x] All tests come before implementation (T004-T009 before T010-T015)
+- [x] Parallel tasks truly independent (different files: [P] marked correctly)
+- [x] Each task specifies exact file path (all tasks include file paths)
+- [x] No task modifies same file as another [P] task (workflow.yml tasks sequential T010-T015)
+- [x] Migration scenarios covered (T022 creates migration guide, T026 validates)
+- [x] Breaking change documented (T023 README, T024 copilot-instructions, T028 CHANGELOG)
+- [x] Both execution modes tested (T004 CI-only, T005 CI+Release)
+- [x] Backward compatibility maintained (workflow API unchanged per contracts/)
