v1.9.0

Changelog

[1.9.0] - 2026-07-14

This release hardens the trust, atomicity, and portability surfaces of Agent
Kernel. The agent proposal helper now enforces strict option parsing and JSON
envelopes, the safe-link and safe Git hook installers ship worktree- and
transaction-aware fixes, and a new portability helper makes retention exports
and imports safe to run against an existing home. Agent runtime write modes
gain a dedicated reference for capture-only and propose-only identities.
