v3.6.0 — Performance & Stability Hardening

P0: Connection pooling (http.client reuse per host), stream idle timeout
    (300s via selectors) on all streaming paths (OA/CC/Gemini/auto-continue)
P1: Retry-After header support on all retry paths, preemptive OAuth token
    refresh (5min before expiry)
P2: oa_convert_tools(strict=) for Responses vs Chat Completions, filter
    null/empty tool names
P3: Response store TTL (600s eviction), bounded stream buffers (8MB cap),
    response.failed/error urgent flush, dual logging (proxy.log)

.deb: v3.6.0 (71KB) — v3.5.0 and v3.3.0 kept as fallback

 - **Browser UA injection** — bypasses Cloudflare bot detection for providers like OpenCode
 - **Smart URL construction** — prevents double-path bugs (`/v1/chat/completions/chat/completions`)
 - **Header forwarding** — preserves client identity headers while filtering hop-by-hop headers
-- **Self-revive watchdog** — auto-restarts proxy on crash (up to 50x, progressive backoff 1→30s)
-- **Debug-to-file logging** — all events and parser results written to `~/.cache/codex-proxy/cc-debug.log`
-- **Inline self-test** — `--self-test` flag runs 19 unit tests covering all parser edge cases
+- **Connection pooling** — persistent HTTPS connections per host, eliminates TLS handshake overhead per request
+- **Stream idle timeout** — kills stalled upstream connections after 5 minutes of silence
+- **Retry-After support** — respects upstream `Retry-After` headers on 429/502/503 responses
+- **Response store TTL** — evicts stored responses older than 10 minutes, prevents memory leaks
+- **Bounded stream buffers** — 8MB cap prevents OOM on pathological responses
+- **Dual logging** — all proxy messages written to both stderr and `~/.cache/codex-proxy/proxy.log`
 - Zero dependencies — pure Python stdlib
