feat(codecontext): upgrade sidecar to boocontext MCP aggregator

- Multi-stage Dockerfile builds boocontext (Node) + HTTP shim (Go)
- shim.go supports CODECONTEXT_CHILD env var for configurable MCP child
- Adds routes for get_symbol_details, get_call_graph, get_blast_radius
- docker-compose.yml adds env vars for child MCP paths

-# Multi-stage build: golang:1.24-alpine builder produces two binaries
