Add cmd_post_comment command for posting Gitea comments without
needing to write temp files. This solves the /tmp permission issue
where PM agent was blocked from writing to /tmp.
Usage:
kugetsu post-comment <repo-url> <issue-or-pr-number> <body>
Example:
kugetsu post-comment https://git.fbrns.co/shoko/kugetsu 81 "Comment text"
The command:
- Reads GITEA_TOKEN from environment or pm-agent.env
- Constructs the API URL from repo URL
- Posts comment directly without temp files
