v0.22.0 — Tool profiles

Trim the MCP to just the tools you need. A new --profile flag (or BLOCKRUN_MCP_PROFILE env) exposes a focused tool set so clients load fewer schemas into context. No flag = the full 18 tools, exactly as before.

# media-only (7 tools)
claude mcp add blockrun-media -s user -- npx -y @blockrun/mcp@latest --profile media
# trading-only (7 tools)
claude mcp add blockrun-trading -s user -- npx -y @blockrun/mcp@latest --profile trading

Profile	Tools
full (default)	all 18
media	wallet · models · image · video · realface · music · speech
trading	wallet · price · dex · markets · surf · defi · rpc
research	wallet · models · chat · search · exa · surf
chat	wallet · models · chat

wallet is in every profile; an unknown name falls back to full. Also adds a profile-resolution test suite and a compile-time guard so the full set can't silently drift.
