Subject: [PATCH] fix(mcpb): sync mcp-server bridge type enum to match Worker
 (9 values)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

mcp-server/server/index.js is the stdio bridge installed via .mcpb into
Claude Desktop / Claude Code. It carries its own JSON inputSchema that the
client validates against before any request is proxied to the Worker. PR #107
expanded Worker-side zod enum to 9 values (adding issue_comment / pr_review /
pr_review_comment), but the bridge's enum was not updated, so requests with
the new types were rejected client-side long before reaching the Worker.

This was the real root cause of #109 (search_issues type=issue_comment being
stuck on the 6-value enum). Yesterday's RagMcpAgent -> V2 rename migration
(PR #110 / #112) updated the Worker side but the bridge-side validation still
blocked requests, so the effect was not visible. V2 deployment is retained;
this fix does not roll back that work.

Update:
- inputSchema.type.enum -> 9 values matching src/mcp.ts
- enum description clarifies the three comment-level types
- tool-level description widens to mention comments, PR reviews, and inline
  review comments

#109 の真因は DO init() cache ではなく bridge 側の JSON schema が 6 値に
停まっていたこと。PR #107 で Worker 側は 9 値に拡張済みだったが bridge
が更新されておらず、client validation でリクエストが弾かれていた。本修正
で bridge を同期する。

Closes #114
Refs #109
