Agent calls checkWalletCapabilities AND explains instead of just executing

[premiumjibles]

Problem

When a user asks to "automate a trade" (e.g. "set up a DCA for ETH over 7 days"), the agent calls both checkWalletCapabilities AND the trade tool (e.g. createTwap), then also explains what automation means — producing a confusing triple response.

tk ticket: sa-gwnv

Root Cause

The checkWalletCapabilities tool description is too broad — it says to call the tool "when the user asks about automated trading features (TWAP, DCA, stop-loss, scheduled trades)" which competes with the specific trade creation tools for the same intents. The system prompt says to pick a single tool, but the LLM sees both as relevant.

Fix (2 files)

1. apps/agentic-server/src/tools/checkWalletCapabilities.ts — narrow the tool description to only trigger for capability inquiries, not trade execution requests
2. apps/agentic-server/src/routes/chat.ts — strengthen <tool-routing> and <tool-ui> sections to disambiguate

Acceptance Criteria

• "Set up a DCA for 100 USDC into ETH" calls only createTwap, not checkWalletCapabilities
• "What can my wallet do?" still calls checkWalletCapabilities
• After successful trade creation, agent responds with one brief sentence
