fix(provider): handle branch names with command keywords in pr comments

This commit fixes a bug in parsing pipeline control comments (e.g., /test,
/retest, /cancel) when branch names contain command keywords like "/test".
Previously, the code would incorrectly split comments with such branch
names, causing failures.

Key improvements:
- Use `strings.SplitN` to split only on the first instance of the command
  keyword.
- Add support for comments with key=value pairs after the pipeline name.
- Include test cases for branch names containing "/test" and comments with
  `key=value` pairs.

Example:
Before: Branch "feature/test-new" would break parsing due to multiple splits
on "/test" keyword.
After: The code now correctly processes branch names with command keywords and
handles key=value pairs.

The parsing is now more robust for real-world scenarios.
