feat(P06): 3-tier versioning, branch hierarchy enforcement, ARCHITECTURE-PLAN synthesis

---ci---
phase: 6
milestone: v0.5
status: complete
decisions:
  - id: D-006
    decision: Research as intermediate work product
    rationale: Conclusions update .ci/ files; full research doc intentionally not preserved
    confidence: 0.90
  - id: D-007
    decision: Branch hierarchy enforcement: main > milestone > phase
    rationale: Prevents out-of-order merges and semantically wrong tags
    confidence: 0.92
  - id: D-008
    decision: 3-tier versioning: NFR/feature/schema-breaking
    rationale: Patch per phase (NFR/feature) or minor per phase (schema-breaking); milestone gets minor (feature) or major (schema-breaking)
    confidence: 0.95
requirements:
  covered: [VER-06, BRANCH-01, BRANCH-02, ARCH-01]

- Synthesize ARCHITECTURE-PLAN.md into .ci/ci/ARCHITECTURE.md (expanded 51→230 lines)
- Add D-006/D-007/D-008 to .ci/ci/PROJECT.md key decisions table
- Delete ARCHITECTURE-PLAN.md after synthesis
- Rewrite ship.md with 3-tier versioning model + branch hierarchy merge flows
- Rewrite branch-strategy.md with 3-tier versioning + branch hierarchy + version validation
- Add MilestoneType to config types
- Replace isNfrMilestone() with getMilestoneType() returning nfr|feature|schema-breaking
- Add validateMergeOrder(), mergeMilestoneBranch(), computeMilestoneTag() to GitBranch
- Add computeShipVersion(), validateVersionOrder(), resolveMergeTarget() to ship command
- Remove hardcoded v0.5. from error-recovery rollback
- Create .githooks/pre-push for semver ordering + branch hierarchy validation
- Add 15 new tests (370 total, all passing)

 ## Versioning and Releases
 
-**Every merge to main creates a release. No exceptions.** Versioning maps to project structure:
+**Every merge to main creates a release. No exceptions.** Versioning follows a 3-tier model based on milestone type:
 
-| Version Part | When | Example |
-|-------------|------|---------|
-| **Major** (X.0.0) | Project-level refactor or schema change | `v1.0.0` |
-| **Minor** (0.X.0) | Every milestone completion | `v0.3.0` |
-| **Patch** (0.0.X) | Every phase completion | `v0.2.3` |
+### 3-Tier Versioning Model
 
-### Phase completion (patch release)
+| Milestone Type | Condition | Phase release | Milestone release |
+|---------------|-----------|---------------|-------------------|
+| **NFR** | All phases: fix/chore/docs/perf/refactor/test | Patch (`vX.Y.Z`) | None |
+| **Feature** | Any phase is `feat`, no schema break | Patch (`vX.Y.Z`) | Minor — `vX.(Y+1).0` |
+| **Schema-breaking** | Refactor/schema break/new direction | Minor — `vX.(Y+N).0` per phase | Major — `v(X+1).0.0` |
 
+**IMPORTANT:** Milestone tags are always the NEXT version, never the base:
+- Feature: patches v0.5.1–v0.5.5 → milestone tag is v0.6.0 (NOT v0.5.0)
+- Schema-breaking: minors v0.3.0, v0.4.0, v0.5.0 → milestone tag is v1.0.0
+- NFR: no milestone tag — the milestone is implicit from the patch sequence
+
+Determine milestone type via `getMilestoneType()` which returns `"nfr" | "feature" | "schema-breaking"`.
+
+### Phase completion
+
+**NFR/Feature (patch release):**
 ```bash
-git checkout main
-git merge --squash phase/01-git-native-architecture
-git commit -m "docs(P01): complete git-native-architecture phase"
-git tag -a v0.2.1 -m "v0.2.1: git-native-architecture"
+git checkout milestone/v0.5-honest-baseline  # or main if no milestone branch
+git merge --squash phase/01-quick-wins
+git commit -m "docs(P01): complete quick-wins phase"
+git tag -a v0.5.1 -m "v0.5.1: quick-wins"
 git push origin main --tags
-# Create Gitea release for v0.2.1
+# Create Gitea release for v0.5.1
 ```
 
 Phase number within the milestone determines the patch version (1st phase = .1, 2nd phase = .2, etc.)
 
-### Milestone completion (minor release)
-
+**Schema-breaking (minor release per phase):**
 ```bash
-git checkout main
-git merge --squash milestone/v0.2-git-native
-git commit -m "docs(milestone): complete git-native"
-git tag -a v0.2.0 -m "v0.2.0: git-native"
+git checkout milestone/v0.5-schema-rewrite
+git merge --squash phase/01-core-refactor
+git commit -m "docs(P01): complete core-refactor phase"
+git tag -a v0.5.0 -m "v0.5.0: core-refactor"
 git push origin main --tags
-# Create Gitea release for v0.2.0 with full milestone summary
+# Create Gitea release for v0.5.0
 ```
 
-### Major release
+Each schema-breaking phase bumps the minor. 1st phase = next available minor, 2nd = minor+1, etc.
 
-When the project undergoes a schema-breaking change (e.g., switching from file-based to git-native architecture), bump the major version. Major releases follow the same merge → tag → release flow.
+### Milestone completion
 
-## NFR Milestone Versioning
+**Feature (minor release):**
+```bash
+# All phases already merged into milestone branch
+git checkout main
+git merge --squash milestone/v0.5-honest-baseline
+git commit -m "docs(milestone): complete honest-baseline"
+git tag -a v0.6.0 -m "v0.6.0: honest-baseline"  # NEXT minor, NOT v0.5.0
+git push origin main --tags
+# Create Gitea release for v0.6.0 with full milestone summary
+```
 
-NFR milestones and feature milestones follow different versioning rules:
+**Schema-breaking (major release):**
+```bash
+# All phases already merged into milestone branch
+git checkout main
+git merge --squash milestone/v0.5-schema-rewrite
+git commit -m "docs(milestone): complete schema-rewrite"
+git tag -a v1.0.0 -m "v1.0.0: schema-rewrite"  # NEXT major
+git push origin main --tags
+# Create Gitea release for v1.0.0 with full milestone summary
+```
 
-**NFR milestones** — all phases are `fix`, `chore`, `docs`, `perf`, `refactor`, or `test`:
-- Each phase gets a progressive patch version (v0.1.1, v0.1.2, v0.1.3)
-- No separate milestone tag — the milestone is implicit from the patch sequence
-- Example: milestone v0.1 with phases P01 (chore), P02 (test), P03 (perf) → v0.1.1, v0.1.2, v0.1.3
+**NFR milestones produce no milestone tag.** The last phase's patch version is the final release.
 
-**Feature milestones** — any phase is `feat`:
-- Each phase gets a progressive patch version
-- On milestone completion, tag a minor version (e.g., v0.2.0)
-- Example: milestone v0.2 with phases P01 (feat), P02 (feat), P03 (fix) → v0.2.1, v0.2.2, v0.2.3 + milestone tag v0.3.0
+### Version Validation
 
-Determine milestone type by checking `isNfrMilestone()` which inspects all phase commit types within the milestone.
+Before creating any tag:
+1. Tag must be strictly greater than all existing tags on the same major.minor line
+2. Milestone completion tag must be next minor (feature) or next major (schema-breaking)
+3. NEVER create a tag that is semantically below existing phase tags
