fix(update): detect launchd-style dashboard/serve cmdlines when scanning stale processes

[nelsonwang2026]

Root cause

The stale-process scanner in _find_stale_dashboard_pids (hermes_cli/main.py) matched the dashboard/serve subcommand via a contiguous substring, e.g. "hermes_cli.main dashboard". Real launch cmdlines interpose flags between the module and the subcommand. On macOS the launchd dashboard agent spawns:

python -m hermes_cli.main --profile orchestrator dashboard --skip-build

The substring never matched, so hermes update left the old backend process running. The frontend kept reporting the previous version via /api/status (frontend/backend version mismatch) until the user manually ran launchctl kickstart -k.

Fix

Switch from contiguous-substring matching to token-based matching: require the standalone token dashboard or serve AND a Hermes process marker (hermes_cli / hermes). This still excludes unrelated cmdlines that merely contain the word "dashboard" (e.g. a chat session mentioning it). Applied to both the POSIX (ps) and Windows (wmic) scan paths.

Regression / verification

• A harness asserts the real launchd cmdline python -m hermes_cli.main --profile orchestrator dashboard ... is now detected.
• A noise cmdline containing "dashboard" as a chat token is rejected.
• Both POSIX and Windows branches match.
• py_compile passes; patch verified to apply cleanly on pristine main (git apply --check).

Scope

Single file hermes_cli/main.py (3 hunks, +30/-13). No behavior change for the normal hermes dashboard foreground path.

Related competing fixes: #44165, #56723, and #56745 address the same stale dashboard/serve scan when flags precede the subcommand. This patch uses broad token-plus-Hermes-marker matching; the others use positional parsing or selector stripping. Maintainer choice is needed.

Thanks for addressing a real stale-runtime gap: current main still uses contiguous dashboard/serve command patterns in hermes_cli/dashboard_procs.py:56-66,103,136, so selectors before the subcommand are missed.

Problems

• Blocking: the proposed _is_hermes_web_server_cmd() at hermes_cli/main.py:6111-6117 only checks whether dashboard/serve occurs anywhere in a whitespace-split command line. It does not verify that token is the subcommand. A non-server Hermes process with a bare dashboard argument satisfies the marker and token checks, then reaches the kill path used by update cleanup (hermes_cli/update_cmd.py:486).
• Current main moved the active scanner into hermes_cli/dashboard_procs.py in c64a4d7; this PR changes only the former main.py location and adds no test file.

Suggested changes

• Port a positional, entrypoint-aware matcher to _scan_dashboard_processes and consume known global selectors before requiring dashboard or serve as the first positional command.
• Add POSIX and WMIC coverage for the profile-prefixed launch form and for prompt/profile-value false positives.

This accepts dashboard or serve anywhere in argv, including a non-server Hermes prompt/argument. Because lines 6113-6117 only establish that it is a Hermes process, the update cleanup can kill that unrelated process. Parse from the Hermes entrypoint and require the first positional subcommand after recognized global flags instead.
