dshx v0.6.0 — Creator+ self-recovery

Creator+ can now protect any number of concurrent sessions working on different plugins without giving model sessions process control.

Highlights:

• bridge-v2 session/plugin claims and exact transaction journals
• detached external Guardian with App-aware recovery, rollback, and a crash-loop fuse
• exact-session incident steering on resume
• same-origin recovery for official Loader failures
• DSH-managed-shell boundary that blocks stale sessions from raw Host mutation
• DSH core remains unchanged

Release gate: 95/95 tests, OKF lint, JavaScript syntax checks, and npm pack dry-run passed.
