feat(codecontext): upgrade sidecar to boocontext MCP aggregator

Browse Source 
- 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

# v1.12 Track B — codecontext sidecar container.
# v2.8 — boocontext sidecar container.
# Multi-stage build: Go shim from golang:1.24-alpine, boocontext MCP aggregator
# from node:20-alpine, then an alpine:3.20 runtime holding both.
#
# Multi-stage build: golang:1.24-alpine builder produces two binaries
# (codecontext from source + our HTTP shim), then a minimal alpine:3.20
# runtime holds both.
# The shim spawns boocontext as a child MCP process over stdio NDJSON,
# translating HTTP requests to MCP tools/call.
#
# No upstream Docker image exists for codecontext. We clone the repo
# directly because the module path declared in go.mod
# (github.com/nuthan-ms/codecontext) differs from the GitHub repo URL
# (github.com/nmakod/codecontext) — `go install` against the GitHub path
# wouldn't resolve. The tagged v3.2.1 source tree is the same either way.
# To stage the fork source for a Docker build:
# tar -czf codecontext/fork.tar.gz -C /opt/forks/boocontext \
# --exclude=.git --exclude=node_modules --exclude=dist
