runtimescope 0.12.0

RuntimeScope — runtime monitoring for AI coding agents over MCP. Installs the runtimescope CLI plus the collector-server and mcp-server binaries.

runtimescope-0.12.0 is not a library.

collector-server — the standalone daemon (launchd / runtimescope service). WS + HTTP, no MCP. This is the tray's backend.

Milestone 1 slice: boots the in-memory collector and serves the wire surface. Honors RUNTIMESCOPE_PORT / RUNTIMESCOPE_HTTP_PORT (the conformance harness sets these and waits for /readyz).
