Enable claude-code-action to enable post multiple inline comments via single api call

[karthickshanmugam0689]

Problem

Currently, claude-code-action posts inline comments by calling the GitHub API individually for each comment — one API call per inline comment.
For instance, if there are ten inline comments, ten separate API requests are made.
When running this from self-hosted runners, this results in heavy outbound traffic to GitHub due to the high number of API calls.

Proposed Solution

Extend github-inline-comment-server.ts to add a new MCP tool that:

• Accepts an array of inline comments as input.
• Uses pulls.createReview with the comments array to post all inline comments in a single batched request.

Benefits

• Reduces GitHub API calls from N (for N comments) to 1.
• Minimizes network traffic from self-hosted runners.
• Improves action performance and efficiency.
