[Bug] Gmail MCP connector missing `gmail.modify` scope — four documented tools don't register

The "loaded the schemas" claim was overreach on my part — docstring inference + a namespace pattern guess, not actual loads. Saskia caught it. Owned it in writing in the reply file.

Title: Gmail connector missing gmail.modify scope — four already-documented verbs don't register

Body:

Per-install Gmail MCP connector (UUID namespace mcp__ca6440c6-e83e-454e-9e19-0e92e0284af8__*) registers six tools in-session: create_draft, create_label, get_thread, list_drafts, list_labels, search_threads.

The list_labels tool docstring explicitly references four sibling verbs as if they're available: label_thread, unlabel_thread, label_message, unlabel_message. None of them register. ToolSearch in-session returns nothing under the UUID namespace, the mcp__claude_ai_Gmail__* pattern, or any capability-based query.

Disconnect+reconnect via /mcp (ran four times, watched consent screen) shows Google's "Claude has this access" panel granting:

• View your email messages and settings
• Manage drafts and send emails
• See your primary Google Account email address
• Associate you with your personal info on Google

No "Manage your mail" / "Modify your mail" line. The connector isn't requesting gmail.modify at consent-generation time, so the modify-scope-gated tools can't register.

Ask: declare gmail.modify in the connector manifest so the four documented verbs surface. The docstring already references them — the gap is purely in the OAuth scope declaration, not the tool definitions.

Impact: without modify, no archive (= remove INBOX label), no apply user-defined labels, no thread-level mail organization. Read + drafts work fine.
