[FEATURE] Gmail MCP Connector: Add gmail_modify_labels tool for archiving, labeling, and inbox management

### Preflight Checklist - [x] I have searched [existing requests](https://github.com/anthropics/claude-code/issues?q=is%3Aissue%20label%3Aenhancement) and this feature hasn't been requested yet - [x] This is a single feature request (not multiple features) ### Problem Statement The hosted Gmail MCP connector at `gmail.mcp.claude.com` currently only supports read operations and draft creation. There is **no way to modify message labels**, which means common inbox management actions are impossible: - **Archiving** emails (removing the `INBOX` label) - **Marking as read/unread** (removing/adding the `UNREAD` label) - **Starring** messages (adding/removing the `STARRED` label) - **Categorizing** messages (adding custom labels) - **Moving to trash** (adding `TRASH` label) **My use case:** I'm running a scheduled Cowork task for automated email triage — it searches for unread emails, classifies them (newsletter/spam vs. relevant), and should archive the noise. Currently, the triage can *identify* what should be archived but cannot *act on it* because there's no way to remove the `INBOX` label. This is a fundamental gap — the connector can read and create drafts, but cannot manage the inbox itself. ### Current available tools (as of March 2026) | Tool | Type | |------|------| | `gmail_search_messages` | Read | | `gmail_read_message` | Read | | `gmail_read_thread` | Read | | `gmail_list_labels` | Read | | `gmail_list_drafts` | Read | | `gmail_get_profile` | Read | | `gmail_cr
