Fix process wait timeout and bind mode; add tests

[nicolaspiet]

Problem

• waitForProcess could return while a process was still starting or running, causing flaky admin CLI behavior.
• CLAWDBOT_BIND_MODE was ignored because the startup script hard-coded lan.

Fix

• waitForProcess now waits through starting and throws on timeout.
• start-moltbot.sh uses CLAWDBOT_BIND_MODE with default lan.

Tests

• npm test

Good catch! Waiting on CI.

Superseded by subsequent changes. The waitForProcess fix was addressed in PR #235 (merged Feb 11), the bind mode is now hardcoded to lan (PR #186), and the entire process management approach has been overhauled in PRs #336/#337 (merged Mar 27-28). This PR was based on the old clawdbot architecture. Thank you for the contribution.
