v6.0.1

Fixes

• Hook false-positive on non-canonical task-close narrations resolved. The routing gate now recognizes a broader assessment vocabulary — closes that summarize work without using the prior fixed keyword list (e.g. "closure assessment: … reclosing legitimate") no longer trigger a spurious block. Thanks to @killett for the detailed report and reproduction steps (#19).
• Hardened dispatch union detection, handoff guard escape logic, and routing gate heuristics to reduce noise in complex multi-agent sessions.

Improvements

• Added missing final step to the upstream double-install removal flow in the onboard command docs.
• Added Test 30 with a native-session transcript fixture to pin the routing gate fix.
