Add Overleaf review comment management commands

[shiquda]

Summary

This PR adds CLI support for managing Overleaf review comments.

New commands:

• olcli comments list [project]
• olcli comments add <file> <message> [project]
• olcli comments resolve <threadId> [project]
• olcli comments reopen <threadId> [project]
• olcli comments delete <threadId> [project]

comments list includes source file, line/column, selected text, messages, status, and optional source context via --context. It also supports status filtering with --status open|resolved|all and JSON output via --json.

comments add can attach a comment to selected text using --text, or to an explicit source range using --line/--column/--length or --position/--length.

Implementation Notes

The implementation mirrors Overleaf's web editor behavior:

• Uses the project Socket.IO endpoint to join documents and read comment ranges.
• Uses /project/:projectId/threads to retrieve thread messages and resolved state.
• Uses document-scoped comment routes for resolve/reopen/delete.
• Adds comments by creating the thread message and applying the document comment range update.

Validation

• Ran npm run build.
• Ran npm test --if-present (no test script is currently configured).
• Ran npm pack --dry-run.

Note: npm run lint is not currently runnable in this repository as-is because the package has a lint script but no ESLint dependency/config. I tested this separately and did not include lint setup in this PR to avoid mixing unrelated lint configuration and existing style cleanup into the feature change.
