release(v0.4.0): purge learnship, migrate .planning→.ci, fix backends, add test coverage

- Remove all learnship references: Decision.learnship_equivalent field,
  agent persona prompts, opencode.json permissions, test fixtures
- Migrate verification layers from .planning/ to .ci/: structural
  checks .ci/ dir + ROADMAP.md, behavioral checks ROADMAP.md
- Fix ollama-local: remove sync require+curl blocking, use async
  fetchAvailableModels() in callModel
- Fix opencode.json: use __OPENCODE_DIR__ template tokens, remove
  legacy learnship permission entries
- Remove duplicate install script from package.json (keep postinstall)
- Fix quality any-regex false positives (target type annotations only)
- Add backends test coverage: backends.test.ts, tool-registry.test.ts
- Version bump 0.3.0 → 0.4.0
- Artifacts module: rename .planning→.ci internal paths
- Remove dead TODO_PATTERN/FIXME_PATTERN constants

phase: 3
milestone: v0.4
status: complete
requirements:
  covered: [REQ-09, REQ-10, REQ-11, REQ-13, REQ-14, REQ-17]
  partial: []
decisions:
  - id: D-001
    decision: purge all learnship references from codebase
    rationale: project is CI-only, learnship is no longer a dependency
    confidence: 0.99
    category: scope
    alternatives: [keep for historical reference]
  - id: D-002
    decision: migrate verification from .planning/ to .ci/ paths
    rationale: .planning/ is removed schema, all current state lives in .ci/
    confidence: 0.95
    category: architecture
    alternatives: [keep dual-path support]
  - id: D-003
    decision: use __OPENCODE_DIR__ template tokens in opencode.json
    rationale: hardcoded ~ paths fail in containers and non-standard homes
    confidence: 0.90
    category: implementation_approach
    alternatives: [keep tilde expansion]

 - **Git-native context**: The git log IS the project memory. Agent's first impulse to gather context is `git log` + `git branch`, not file reads. Dynamic state (decisions, escalations, lessons, compounding) lives in `---ci---` YAML blocks in commit messages. `.ci/` holds only long-lived reference docs (PROJECT.md, ARCHITECTURE.md, ROADMAP.md, REQUIREMENTS.md, config.json).
 - **Artifact compatibility**: CI no longer writes `.planning/` schema. Dynamic state is derived from git history. `.ci/` files follow a CI-native schema.
