564e0a9c67 Add per-listener connection limits 
Configurable maximum concurrent connections per listener. When the
limit is reached, new connections are closed immediately after accept.
0 means unlimited (default, preserving existing behavior).

Config: Listener gains max_connections field, validated non-negative.

DB: Migration 3 adds listeners.max_connections column.
UpdateListenerMaxConns method for runtime changes via gRPC.
CreateListener updated to persist max_connections on seed.

Server: ListenerState/ListenerData gain MaxConnections. Limit checked
in serve() after Accept but before handleConn — if ActiveConnections
>= MaxConnections, connection is closed and the accept loop continues.
SetMaxConnections method for runtime updates.

Proto: SetListenerMaxConnections RPC added. ListenerStatus gains
max_connections field. Generated code regenerated.

gRPC server: SetListenerMaxConnections implements write-through
(DB first, then in-memory update). GetStatus includes max_connections.

Client: SetListenerMaxConnections method, MaxConnections in
ListenerStatus.

Tests: DB CRUD and UpdateListenerMaxConns, server connection limit
enforcement (accept 2, reject 3rd, close one, accept again), gRPC
SetListenerMaxConnections round-trip with DB persistence, not-found
error handling.

Also updates PROJECT_PLAN.md with phases 6-8 and PROGRESS.md with
tracking for the new features.

498f040cbe Add L7 and PROXY protocol fields to gRPC API and CLI 
Proto: Route message gains mode, tls_cert, tls_key, backend_tls,
send_proxy_protocol fields. ListenerStatus gains proxy_protocol.
Generated code regenerated with protoc v29.5.

gRPC server: AddRoute validates mode ("l4"/"l7", defaults to "l4"),
requires tls_cert/tls_key for L7 routes, persists all fields via
write-through. ListRoutes returns full route info. GetStatus
includes proxy_protocol on listener status.

Client package: Route struct expanded with Mode, TLSCert, TLSKey,
BackendTLS, SendProxyProtocol. AddRoute signature changed to accept
a Route struct instead of individual hostname/backend strings.
ListenerStatus gains ProxyProtocol. ListRoutes maps all proto fields.

mcproxyctl: routes add gains --mode, --tls-cert, --tls-key,
--backend-tls, --send-proxy-protocol flags. routes list displays
mode and option tags for each route.

New tests: add L7 route via gRPC with field round-trip verification,
L7 route missing cert/key (InvalidArgument), invalid mode rejection,
default-to-L4 backward compatibility, proxy_protocol in status.

f24fa2a2b0 Switch gRPC admin API to Unix socket only, add client package 
- Remove TCP listener support from gRPC server; Unix socket is now the
  only transport for the admin API (access controlled via filesystem
  permissions)
- Add standard gRPC health check service (grpc.health.v1.Health)
- Implement MCPROXY_* environment variable overrides for config
- Create client/mcproxy package with full API coverage and tests
- Update ARCHITECTURE.md and dev config (srv/mc-proxy.toml)
