* perf: optimize session loading and startup
* fix(chat): stabilize history prepend virtualization
* perf: unblock first session open from startup network contention
Opening the first session after app start waited seconds for its message
fetch. Three independent contributors, each measured via CDP network
capture and Chromium net-log against the packaged desktop app:
- The active-session watchdog fired an uncapped per-directory status poll
and child-session discovery burst at startup, and other subsystems
(git checks, global session pages, command/skill discovery) fanned out
alongside it, saturating the browser's ~6 HTTP/1.1 sockets per origin.
Add a shared background-network gate (concurrency 3) and route the
watchdog, poll-shaped git reads (also priority: low), global session
pages, command/skill loads, and the background update check through it.
- The packaged renderer is cross-origin to the loopback backend, so every
API call needs a CORS preflight; a few slow OpenCode-proxied requests
held the whole pool while preflights and interactive traffic queued
behind them. Lift Chromium's per-host connection cap for loopback via
ignore-connections-limit in the Electron shell.
- OpenCode initializes each directory lazily on its first request, so the
first click paid that cost interactively. Warm the last-used directory
and the three most recently opened projects right after OpenCode
readiness, sequentially and best-effort, overlapping UI startup.
Validation: new background-network tests, lifecycle warmup test, focused
store/sync tests, UI type-check and lint, dead-code report, node --check
plus electron type-check/lint, and CDP first-open measurements on the
packaged app (message fetch socket queue 5.4s -> 0.03s).

* feat(tts/stt): add API key support for OpenAI-compatible custom providers
## Problem
Custom (OpenAI-compatible) TTS/STT provider in Voice Settings has no way to
pass an API key or bearer token. Many self-hosted or third-party compatible
servers require authentication, making them unreachable from OpenChamber.
The server-side TTS route already accepts an `apiKey` parameter, but the
frontend never sends it. The STT route hardcodes `'not-required'`.
## Implementation
- Add `openaiCompatibleApiKey` to Zustand config store, persisted to localStorage
- Add API Key input field in VoiceSettings.tsx under the custom provider section
- Wire `openaiCompatibleApiKey` through useServerTTS to the TTS backend
- Add `apiKey` field to AudioStreamConfig for STT, forwarded as X-API-Key header
- Update server STT route to accept and forward X-API-Key to transcribeAudio
- Update stt.js to use client-provided apiKey before falling back to env var

* feat(tts/stt): add separate API key support for custom TTS and STT providers
## Problem
Custom (OpenAI-compatible) TTS and STT providers in Voice Settings have no way
to pass API keys. Many self-hosted or third-party compatible servers require
authentication, making them unreachable from OpenChamber Desktop (Electron).
## Implementation
- Add `openaiCompatibleApiKey` for TTS (persisted to localStorage, passed in JSON body)
- Add `sttApiKey` for STT (persisted to localStorage, passed via Authorization: Bearer header)
- Two independent keys: TTS and STT are configured separately
- STT authentication follows OpenAI standard (Authorization: Bearer <token>)
- TTS authentication follows existing pattern (apiKey in JSON body)
- Backend STT route extracts bearer token from Authorization header
- Backend STT service prefers client-provided key over OPENAI_API_KEY env var
## Fixes
- Fixed P1: ConfigStore interface now declares setOpenaiCompatibleApiKey setter
- STT API key is only forwarded when sttProvider === 'server' (not leaked to other providers)

* fix: refresh server STT callback when API key changes
* fix(tts): allow remote custom provider URLs on desktop runtime
## Problem
Custom OpenAI-compatible TTS/STT provider URLs are restricted to
localhost addresses only. Remote URLs are silently rejected at the
server boundary, making custom cloud-based TTS/STT providers unusable
in the desktop app.
## Root Cause
`base-url.js` rejects non-localhost URLs unless
`OPENCHAMBER_ALLOW_REMOTE_OPENAI_COMPAT_URLS=true` is set, but this
env var is never set by desktop shells and is not exposed in settings.
## Solution
Use the existing `OPENCHAMBER_RUNTIME` env var (already set to
`'desktop'` by both Electron and Tauri shells) to auto-allow remote
custom URLs on desktop. Web deployments retain SSRF protection by
default. The explicit env var override still works for either direction.
Closesopenchamber/openchamber#1438
* fix(tts): respect explicit env var override on desktop runtime
## Problem
The previous implementation used `|| isDesktop` which unconditionally
allowed remote URLs on desktop, making `OPENCHAMBER_ALLOW_REMOTE_OPENAI_COMPAT_URLS=false`
a no-op. The PR description documented this as supported but it didn't work.
## Fix
Changed precedence logic: explicit env var (set or unset) takes absolute
priority in both directions. When no explicit flag exists, desktop runtime
defaults to allowing remote URLs. This lets operators tighten desktop
deployments with env var =false.
## Test
Added test case: desktop + env var =false → remote URLs denied (8 pass, 0 fail).
Addresses PR review: P1 (env var precedence) and P2 (missing deny test).

Disable the active Zen summarization flow because the unauthenticated/free Zen provider is no longer available and now returns usage-limit errors for this feature.
Keep /api/text/summarize as an API-compatible stub that returns local sanitized or distilled fallback text with summarized=false, rather than attempting external model calls.
Remove notification and voice playback summary behavior from runtime paths. Notification {last_message} now always uses normalized truncated text, and TTS playback ignores historical summarize request fields.
Hide the notification summary settings and voice summarize-before-playback controls while preserving legacy persisted settings for compatibility. Also disable Zen model startup validation and make Zen model list routes return empty results.
Update module documentation and tests to describe the retired provider behavior and the remaining compatibility stubs.
