30e0a83a50 feat(network): SSE optimization for local LLM streaming (#31 #32 #33) (#26)
CI / CI (push) Successful in 3m35s
Addresses three critical network issues for LLM streaming performance:

**#33 Disable proxy buffering for SSE**
- Add X-Accel-Buffering: no header to response
- Tells nginx/Ingress to stream events immediately instead of buffering

**#32 HTTP/2 multiplexing for concurrent streams**
- Enable HTTP/2 in server config via http2.ConfigureServer()
- Increase MaxConnsPerHost to 10 for better concurrency
- Allows multiple concurrent LLM requests without blocking

**#31 TCP backpressure for streaming LLM responses**
- Set TCP_NODELAY on dialer to disable Nagle's algorithm
- Reduces latency by sending small packets immediately
- Critical for low TTFT (time-to-first-token) under load

**Tests added:**
- TestTCPBackpressure: Verifies TCP backpressure handling with slow client
- TestConcurrentSSEStreams: Confirms HTTP/2 multiplexing works correctly

Story Crater Bot 6cf5c3e5a9 fix(server): stop WriteTimeout from killing in-progress LLM streams
Build / Build and push image (push) Successful in 34s
CI / Test, vet, build (push) Successful in 2m16s
http.Server.WriteTimeout is an absolute deadline over the whole
response, not an inactivity timeout -- 15s was cutting off SSE streams
from the reasoning model mid-generation, surfacing to clients as a
"terminated" error well before the model finished. Switch to
ReadHeaderTimeout (protects against slow headers without capping body
duration) and raise WriteTimeout to match the edge nginx Ingress's
proxy-read/send-timeout of 3600s.

Baseline for the Kong replacement on api.riotpiao.com. Brings the working
tree under version control for the first time: gateway source, the task
board that drives the agent runs, test fixtures, and K8s manifests.

Anchor the gateway ignore rule to the repo root. Unanchored, "gateway"
also matched the cmd/gateway/ source directory, so the program entrypoint
was excluded from every commit.
