feat: add human-friendly connected-app action prompts

[iamjr15]

Summary

• Replace raw provider API descriptions in connected-app drawers with product-owned starter prompts.
• Keep actions immediately usable while collecting only missing details in plain language.
• Require confirmation before destructive actions and preserve connected-app branding.

Architecture

Composio remains the bounded source of tool schemas for the agent. The gateway now owns a separate presentation boundary that maps provider tool metadata to the strict { name, prompt, slug } UI contract. The web renders and launches that prompt without deriving copy from provider documentation.

Decisions Made

Decision	Choice	Alternatives considered	Reasoning
UI copy ownership	Gateway-owned shared formatter	Display description or human_description	Both provider fields contain API concepts and identifiers; product copy must be stable and user-facing.
Safety	Confirmation language for destructive actions	Generic prompt for every action	Delete, revoke, and similar operations need explicit confirmation before execution.
Compatibility	One toolkit-agnostic formatter	Per-connector prompt tables	A shared action-family model covers every current and future Composio toolkit without connector patches.

Edge Cases Handled

• Missing optional tool names fall back to readable slugs.
• Singular, plural, uncountable, and vowel-sound wording stays grammatical.
• Toolkit display names retain official capitalization.
• Oversized but valid provider descriptions remain bounded and parseable.
• Deprecated actions remain excluded.

How to Review

1. Start with integration-action-presentation-support.ts for the presentation policy.
2. Check integrations-catalog.ts and packages/types/src/api.ts for the API boundary.
3. Check integration-skill-drawer.tsx for the direct prompt-launch behavior.
