Release DA — v0.51.129 (stage-batch11, 4-PR feature + perf batch)

What's in this batch

Performance (HIGH-RISK, Opus-reviewed)

#2836 by @v2psv — HTTP/1.1 keep-alive. Bumps Handler.protocol_version to HTTP/1.1 and properly frames all responses with Content-Length / Connection: close. Significant gains on high-RTT paths (~47% first paint, ~30-40% panel loads per author measurements). Includes Opus MUST-FIX patched inline: Connection: close on the on-the-fly folder ZIP download endpoint (the only remaining streaming response missing the framing header).

New features

#2680 by @mccxj — Auxiliary Models settings card. 9 task slots (vision, web extract, compression, session search, approval, MCP, title generation, skills hub, curator), each with provider + model dropdowns and "auto" fallbacks. New GET /api/model/auxiliary + POST /api/model/set endpoints. 16 i18n keys across all 12 locales (Turkish translations added in-stage to close sibling-collision with v0.51.127). Browser-verified at 1920×1080.
#2842 by @AJV20 — Polished installed PWA startup. New static/pwa-startup.js loaded synchronously in <head> marks standalone/browser/iOS/offline classes before first paint, exposes HermesPWA namespace with 4 helpers, captures install events early. Manifest gains display_override, app identity, "New conversation" shortcut. Service worker pre-caches the startup helper + switches navigation/shell asset fetches to cache: 'no-store'. Boot path handles ?source=pwa&action=new-chat. Viewport meta sets maximum-scale=1, user-scalable=no for PWA-native feel (acknowledged WCAG 2.1 trade-off — Nathan-approved).
#2794 by @Michaelyklam — Runtime adapter route selection harness. Continues #1925 slice progression (slice 4e). Routes explicit adapter-mode chat starts through build_runtime_adapter(...), keeps legacy-direct as default. Returns bounded 501 Not Configured for runner-local without a supervised runner client. Whitelist helper keeps adapter-internal fields out of public chat-start responses.

Cherry-pick mechanics

#2794 + #2836: clean rebase against current master
#2680: rebase failed on static/index.html; resolved via git apply --3way of net delta — applied cleanly
#2842: same pattern, applied cleanly including new static/pwa-startup.js

Verification

✅ Full pytest: 6,467 passed / 6 skipped / 3 xpassed / 8 subtests passed in 2m32s
✅ Agent self-verify covered HTTP framing assertions, Auxiliary Models API surface, PWA helpers + manifest, Runtime adapter wiring + response whitelisting, i18n parity across 12 locales
✅ Browser-verified at 1920×1080: Auxiliary Models card layout clean and consistent; PWA classes detected on <html>; HermesPWA namespace populated
✅ Opus pre-release advisor reviewed all 7 risk areas: 1 MUST-FIX patched inline (folder ZIP Connection: close), 0 inline SHOULD-FIX, 1 follow-up suggested
✅ JS syntax, Python syntax, JSON manifest all clean
✅ Merge-marker grep clean

Follow-up to file (post-tag)

set_auxiliary_model task validation: accepts arbitrary task strings without validating against AUX_TASK_SLOTS whitelist. Auth-gated so low severity, but a buggy or hostile client could write arbitrary keys to config.yaml's auxiliary block. 2-line guard fix.

Closes

#2853 (already closed by v0.51.127, just confirming dead-line)
(auxiliary feature does not auto-close any issue; #2680 is a feature addition)

🤖 Generated and reviewed end-to-end by the agent pipeline (Phase 4 stage build via 3-way apply for 2 PRs + rebase for 2 PRs → agent self-verify → pytest gate → browser verification → Opus pre-release advisor with 1 MUST-FIX patched inline).
