Open Second Brain v0.43.1 - Hermes CLI discovery contract completed

Patch release: standalone installs of the Hermes plugin now actually expose the documented hermes open-second-brain CLI subtree. Hermes discovers plugin CLI commands by scanning exactly one file - <plugin_root>/cli.py - while the implementation lives in plugins/hermes/cli.py, so the documented subcommands were never discoverable on a stock Hermes; an 18-line root re-export shim through the loader's synthetic parent packages closes the gap, and a loader-contract test mirrors the upstream scan's exact import sequence so it cannot reopen silently.

What ships

Artifact	Role
cli.py (repo root)	SDK-free relative re-export of register_cli / run through the synthetic parent packages the upstream loader registers (hermes-agent PR #37366)
HermesLoaderContractTests	Reproduces the upstream scan's import sequence - synthetic parents pre-registered, root __init__.py never executed - pinning the contract on both sides

Notes

• Python plugin suite grows 60 -> 61 tests; TypeScript suite unchanged at 3973 (510 files), typecheck and lint baselines preserved.
• No TypeScript surface changes; this release only completes the Hermes integration contract.
