Fix workflow entrypoint and script imports

[MahanKenway]

Motivation

• Ensure the collector runs reliably in CI and when invoked directly by resolving package imports and using a module entrypoint.

Description

• Run the collector via python -m src.main in the GitHub Actions workflow so package imports resolve correctly in CI.
• Update scripts/collector.py to prepend the repository root to sys.path before importing src.main so the script can be executed directly without import errors.

Testing

• No automated tests were executed for this change; edits are limited to the workflow and the script entrypoint.

Prioritize repo root on sys.path for local imports

Appending the repo root with sys.path.append(...) puts it at the end of the import search path, so if the environment already has a third‑party package named src installed, from src.main import main can resolve to the wrong module. This can cause python scripts/collector.py to run unrelated code or fail only on machines with that package present. Use sys.path.insert(0, ...) or similar to ensure the local src package takes precedence.
