chore(release): bump ACP Registry assets in lockstep with pyproject

The ACP Registry manifest (acp_registry/agent.json), the npm launcher
package.json, and the launcher's HERMES_AGENT_VERSION constant must all
match pyproject.toml exactly — tests/acp/test_registry_manifest.py
enforces this lockstep.

Without a release-script hook, the next weekly version bump fails that
test until someone hand-edits four files. Extend update_version_files()
to drive the ACP bump alongside __init__.py and pyproject.toml, and
add tests covering the lockstep and the missing-files no-op path.

Also map adam.manning@gmail.com -> am423 for the salvage commit.

+"""Tests for the ACP Registry version-lockstep bump in scripts/release.py.
+
+The official ACP Registry manifest, the @nousresearch/hermes-agent-acp npm
+package, and the npm launcher's HERMES_AGENT_VERSION constant must all match
+``pyproject.toml`` exactly — ``tests/acp/test_registry_manifest.py`` enforces
+this at lint time. The release script is the single place that bumps them in
+lockstep with pyproject; if that bump ever silently breaks, weekly releases
+fail the manifest test until someone hand-edits four files.
