Dual-Harness Migration & Event Loop Fix

Run migrate-dual-harness.sh to migrate a single-harness repo (Claude-only or Codex-only) to the vendor-neutral dual-harness layout where both Claude Code and Codex share the same instructions and skills — checkup §10 and a new foundry skill handle the split automatically. A daemon event loop stall that caused 72–97 second heartbeat gaps during worktree cleanup bursts is also resolved, along with a fix that stamps provider delivery IDs onto webhook envelopes so the smee-vs-cloud parity harness can actually join on them.
