feat(claire): add 4 Claire MCP tools

[paarths-collab]

Summary

• Adds 4 Claire MCP tools to give Max's chat agent the same Claire access onboarding has
• Thin proxy over the existing /api/v1/claire/* routes already on max-agent main — same service-secret + on-behalf-of pattern, no per-user Claire token needed
• Pattern matches Apollo / Explorium (schema.ts, repository.ts, tools.ts), registered via registerClaireTools in mcp/register.ts

Tools added

Tool	Purpose
claire_search	Free-text research query (mode: lite/full)
claire_deep_research	Multi-source background on a person or company
claire_market_watch	Monitor a URL for market signals
claire_find_competitors	Identify direct competitors of a company URL

All four are synchronous from the tool's POV — max-agent's shared runHubJob() handles Claire submit + poll internally and returns the final result.

How it flows

Max chat (Bearer JWT)
    → max-mcp-server (claire_*)
        → max-agent /api/v1/claire/* (authenticate, extract user.email)
            → claire-api with X-Service-Secret + X-On-Behalf-Of

Test plan

• Deploy preview, point a Max chat session at it
• In Max chat: "Research stripe.com and tell me what they do" → expect claire_deep_research call with entity_type: "company" returning result
• In Max chat: "Find competitors of stripe.com" → expect claire_find_competitors returning a list
• Verify no new env vars needed — DIGITALCREW_API_BASE_URL already covers it
• Verify tsc --noEmit clean (verified locally)
