) Prepare 0.94.0 (minor) from main c0ec99d. Adds only the four version and notes metadata changes. No source, client or static changes. Carries #2065 (Windows local HTTPS trust with one Windows confirmation), #2061 (optional host-account sign-in bridge, off by default) and #2058 (worktrees component publisher). Minor because #2061 adds a documented opt-in setting and sign-in workflow. Notes: one entry, notices empty. Co-authored-by: Amplifier <240397093+microsoft-amplifier@users.noreply.github.com>

An isolated Unified service currently accepts only its guest OS account, so its owner cannot sign in with the normal host credentials used by other Constellation agents. Add an opt-in
host_pamsetting that uses the existing Constellation private owner-login socket. The default process-owner PAM path stays unchanged.The bridge accepts one configured host owner; failed, malformed, unavailable or non-private sockets deny login without falling back to a guest password. Authentication remains separate from the service's OS identity, sessions, files and agent permissions. Normal HTTPS, CSRF and session-cookie behavior is retained. Deployment guidance documents setup and recovery.
Validation in a disposable Linux ARM64 DTU: 46 focused tests passed, with two native Windows publication tests skipped. The exact canonical Instance bridge also passed real synthetic-account PAM rejection/acceptance through Unified's normal HTTPS login and authenticated UI/state routes. No model calls, production credentials or live Anchor changes. Initial test setup requested an unavailable
devextra; installing the named test dependencies corrected the harness before the passing run. Actual Incus forwarding and live adoption are separate follow-through.
