chore(ultraplan-local): bump v3.4.1 + plugin.json description drift fix

Step 13 of v3.4.1 plan.

- plugin.json description: Five-command -> Six-command (drift fix); also
  drops the trailing ultra-cc-architect sentence (SC-6 collateral).
  Mentions multi-session resumption as part of the Six-command pipeline.
- plugin.json + package.json version: 3.4.0 -> 3.4.1.

361 tests still green.
