Implement self-contained runtime: install runtime tree, git-root memory, canonical agent paths, + 4 suites

- install.sh: install runtime tree under OPENCODE_DEV_AGENT_TEAM
  (bin/, 12 skills, improvements/, install-manifest.json), idempotent
  shell-rc export, --uninstall (preserves improvements/ user data) and
  --migrate; preserves 13-agent copy, .backup retention, KEEP_BACKUPS=5,
  count gate, cmp -s integrity, install-time permission gate
- memory-lifecycle.sh: resolve MEMORY_DIR from project git root + OPENCODE_MEMORY_DIR
- all 13 agents: canonical runtime sentence + env-resolved runtime paths;
  project-scoped refs unchanged
- tests: new test-install (15), test-runtime (10), test-path-resolution (12),
  test-memory-isolation (12); TEAM_ROOT override on existing 4 suites;
  test-all.sh registers 8 suites (100 checks total)

 ## Memory & Skills Awareness
 
 Before implementing, check project memory for relevant context:
-- `scripts/memory-lifecycle.sh recall decisions <keywords>` — for architectural decisions affecting your scope
-- `scripts/memory-lifecycle.sh recall lessons <keywords>` — for proven implementation patterns
-- `scripts/memory-lifecycle.sh recall failures <keywords>` — for past implementation mistakes to avoid

-- Implementation mistake with prevention → `scripts/memory-lifecycle.sh store failures <file>`
