feat: Implement github_comment in write_tools.py + test

[mabry1985]

I'll start by reading the canonical instructions and the relevant files.I'll start by reading the canonical instructions and the relevant files.Let me check the gh_cli.py helpers to confirm signatures.I have everything I need. The pattern from github_create_issue is clear. Let me implement github_comment.Now let me append tests for github_comment to the test file, following the existing conventions.Done. Both files are implemented and the acceptance criteria are met.

Changes

write_tools.py — replaced the github_comment stub body (only that function touched):

• Validates the repo with bad_repo() (early return on invalid).
• Builds ["issue", "comment", str(number), "--repo", repo, "--body", body] — number is stringified since it arrives as int.
• Runs via run_gh, checks errors via check_gh_error, returns out.strip() (the comment URL gh prints).
• Updated the docstring (plain string literal, per §6) — dropped the TODO(team) line, added "Returns the new comment URL."

The module-top from .gh_cli import bad_repo, check_gh_error, run_gh was already present from the prior feature, so no import change was needed.

tests/test_write_tools.py — appended four tests mirroring the existing github_create_issue conventions (patching run_gh in the ghplugin.write_tools namespace, ainvoke):

• test_comment_returns_comment_url — asserts URL returned and exact argv (issue comment 42 --repo o/n + --body).
• test_comment_number_is_stringified — confirms the int number reaches gh as "7".
• test_comment_bad_repo_short_circuits — invalid repo returns Error: with owner/name, never shells out.
• test_comment_gh_failure_returns_check_gh_error — nonzero exit → Error (gh exit 1): ....

All paths from the definition of done (success URL, bad repo, gh failure) are covered, and existing github_create_issue tests are untouched.

CI Status

• test: queued

Diff Review

• Replaces github_comment stub with a working gh issue comment call via run_gh/check_gh_error, mirroring the github_create_issue pattern exactly (write_tools.py:63-68)
• Four tests appended covering success URL return, int→str conversion, bad-repo short-circuit, and gh failure error string (tests/test_write_tools.py:75-116)
• No imports needed — bad_repo, check_gh_error, run_gh already imported at module top

Observations

• No blocking findings. Implementation is clean, follows existing conventions, and all test paths are covered.
• LOW: Docstring format is a plain string literal — consistent with §6 and the existing tool docstrings in this file; not a defect.
