mram e363c9e4e4 Native Windows deployment: config file, service, signed auto-update 
- internal/config: .env-style config file (gpu-turnstile.env next to the
  exe, -config flag or GPU_TURNSTILE_CONFIG); process env overrides file.
- internal/service: Windows service via golang.org/x/sys/windows/svc —
  graceful SCM stop, 'service install/remove' commands, restart-on-failure
  recovery (also applies staged updates). First external dependency,
  Windows-only; Linux/Docker build unaffected (go.mod stays at 1.23).
- internal/update: polls the Gitea releases API, verifies the Ed25519
  signature of the downloaded binary against an embedded public key
  (openssl-signed by CI), swaps it in next to the running exe, and once
  the GPU lock is idle exits with code 3 so service recovery restarts
  onto the new version. Dev builds and empty pubkey never update.
- CI: tag builds additionally produce gpu-turnstile.exe + .sig + .sha256
  attached to a Gitea release.
- LOG_FILE env var so the service has somewhere to log.

mram 42e1386811 Extend retry backoff; rework logging (LOGLEVEL, request lines, colors) 
Backoff now covers all dial-phase errors (refused, timeout, DNS), TLS
handshake failures, and 5xx responses with replayable bodies; streamed
POSTs are never replayed to avoid duplicate work. First retry of an
episode logs at WARN, subsequent attempts at INFO.

LOGLEVEL (LOG_LEVEL kept as alias) now defaults to warn: startup logs
version plus every setting; INFO adds one line per incoming request and
per response with status/duration, ANSI-colored in text mode (bypasses
slog's escaping so colors render in docker compose logs); NO_COLOR or
LOG_FORMAT=json disables colors.

mram 20d5439b5f Retry upstream connection-refused with exponential backoff 
A refused dial (service down/restarting) is retried with a wait that
doubles from BACKOFF_INITIAL (1s) up to BACKOFF_MAX (60s) until the
upstream answers or the client disconnects. Handles the Windows WSA
errno (10061) as well as POSIX ECONNREFUSED. compose.yaml.example now
uses host.docker.internal like the working local deployment.

mram cf9be55a6c Make poll intervals and operational timeouts configurable
ci / test (push) Successful in 47s
Details
ci / docker (push) Failing after 30s
Details 
New env vars: UNLOAD_POLL_INTERVAL, HISTORY_POLL_INTERVAL, PROBE_TIMEOUT,
FREE_TIMEOUT, WARM_TIMEOUT, SHUTDOWN_TIMEOUT, PROMPT_CAPTURE_LIMIT.
Defaults unchanged; invalid values fail fast at startup.

mram db11da8307 Rename to gpu-turnstile; swap port roles 
The proxy now listens on the standard service ports (Ollama :11434,
ComfyUI :8188) and the actual services move one port up (:11435, :8189).
Metric prefix is now gpu_turnstile_.

mram 065c294a96 gpulock: GPU arbitration proxy for Ollama + ComfyUI 
Implements SPEC.md: two listeners, one writer-preferring two-mode lock,
Ollama unload before image jobs, ComfyUI history polling + VRAM free,
optional model warm-up, healthz/metrics endpoints, streaming-safe
reverse proxies, Dockerfile and Gitea Actions CI.
