Adds the 9 subagent role definitions from agent-pipeline v0.5.0 that
.agent-context-manifest.yml already tracks by sha256. Files were installed
by bootstrap-agent-context during Phase 0 but missed in the preceding
bridge commit.
All 9 hashes verified against the manifest. Pipeline-version drift against
agent-pipeline's freshly-landed Phase 1a slim versions of the 3 audit roles
+ Phase 2a MCP-patched conductor/architect will be detected by the
agent-context-drift workflow on the next scheduled run — that's the intended
sync-agent-context loop, not a regression.
