fix: allow dev/main builds to bypass version check

Version check was blocking dev/main builds (e.g., '0.0.0-main-da9da6f')
from using temperature proxy, even though they have the latest code.

Added regex to skip version check for builds matching:
- ^0\.0\.0-main (main branch builds)
- ^dev (dev builds)
- ^main (main version strings)

These builds are assumed to have proxy support since they're built from
the latest codebase.

Fixes testing workflow when installing Pulse with --main flag
