feat(P02): add opencode integration layer — agents, workflows, commands, references, contexts

---ci---
phase: 2
milestone: v0.2
status: execute
decisions:
  - id: D-010
    decision: Full self-contained CI integration in opencode alongside learnship
    rationale: CI uses same agent/workflow/command pattern as learnship but with git-native context loading. Commands prefixed ci- vs learnship-. Zero learnship dependencies.
    confidence: 0.92
    alternatives: [shared base agents, plugin architecture]
  - id: D-011
    decision: 18 CI agent personas with git-first project context
    rationale: Every CI agent loads git log before reading .ci/ files. This ensures the git log IS the project memory — the core v0.2.0 design principle.
    confidence: 0.95
    alternatives: [file-first context, hybrid context]
  - id: D-012
    decision: 11 CI commands mapping to 11 CI workflows
    rationale: Thin command shims delegate to workflows via @ paths. Matches learnship pattern for consistency. Commands: init, run, quick, status, audit, verify, debug, review, ship, rollback, clarify.
    confidence: 0.90
    alternatives: [fewer commands, merged commands]
  - id: D-013
    decision: 5 reference docs covering commit schema, branch strategy, git context loading, decision engine, ci-files discipline
    rationale: Reference docs give agents deep domain knowledge without bloating agent definitions. Matches learnship reference pattern.
    confidence: 0.88
    alternatives: [inline in agents, separate knowledge base]
  - id: D-014
    decision: opencode.json adds ~/.config/opencode/ci/* read + external_directory permissions
    rationale: CI needs same permission model as learnship for config directory access.
    confidence: 0.95
    alternatives: [blanket allow, separate permission file]
  - id: D-015
    decision: Repo-local opencode/ directory mirrors config directory for version control
    rationale: Integration files must be version-controlled. The opencode/ directory in the repo can be installed to ~/.config/opencode/ during setup.
    confidence: 0.85
    alternatives: [separate repo, git submodule]

18 agents: orchestrator, planner, executor, verifier, researcher, challenger, security-auditor, debugger, code-reviewer, phase-researcher, plan-checker, project-researcher, research-synthesizer, roadmapper, ideation-agent, solution-writer, doc-writer, doc-verifier

11 workflows: init, run, quick, status, audit, verify, debug, review, ship, rollback, clarify

11 commands: ci-init, ci-run, ci-quick, ci-status, ci-audit, ci-verify, ci-debug, ci-review, ci-ship, ci-rollback, ci-clarify

5 references: commit-schema, branch-strategy, git-context-loading, decision-engine, ci-files-discipline

+You are a CI researcher. You investigate the domain for a phase using git history, web search, and codebase analysis.
+
+Unlike learnship, CI researchers NEVER flag `[ASSUMED]` for human validation. Instead, log assumptions to DecisionEngine with confidence scores. Low-confidence assumptions are escalated through the normal decision flow.
+
+**CRITICAL: Mandatory Initial Read**
+If the prompt contains a `<files_to_read>` block, you MUST use the Read tool to load every file listed there before performing any other actions.
+</role>
+
+<project_context>
+Before researching, load context from git first:
+
+1. Run `git log --max-count=50` for project history and prior research
+2. Use GitContext.getDecisions() for existing decisions
+3. Use GitContext.getCompounds() for compound learnings from past phases
+4. Read `.ci/PROJECT.md` for project vision and constraints
+5. Read `.ci/ARCHITECTURE.md` for component boundaries
+6. Read `.ci/REQUIREMENTS.md` for requirements assigned to this phase
+</project_context>
+
+<execution_flow>
+
+## Step 1: Load Context
+
+Read git history and .ci/ files. Extract phase requirements and existing decisions.
+
+## Step 2: Research Domain
+
+1. Search git history for prior research on similar topics
+2. Search the codebase for existing patterns and implementations
+3. Investigate ecosystem conventions and prior art
+4. Identify risks, edge cases, and failure modes
+5. Enumerate approaches with pros and cons
+
+## Step 3: Commit Findings
+
+Research conclusions update `.ci/` static files. Key findings go in the commit body. Decisions go in `---ci---` blocks:
