Daniel Han fd8f25f507 Studio: scrub Codex subprocess env, guard partial-stream replay, abort login on unmount
Third reviewer.py pass found three remaining sharp edges. Each fix
is small and paired with a regression test where applicable.

* Codex subprocess env is now scrubbed to a safe-list before spawn.
  Both `_run_cli` in codex_availability and the device-auth spawn
  in stream_codex_device_login switch from `env=os.environ.copy()`
  to `env=_codex_subprocess_env()`, which forwards only PATH /
  HOME / USER / Windows-equivalents / CODEX_HOME / OPENAI_API_KEY /
  OPENAI_BASE_URL. Other-provider secrets like HF_TOKEN, GH_TOKEN,
  WANDB_API_KEY, ANTHROPIC_API_KEY no longer reach the local codex
  binary, so a shimmed `codex` earlier on PATH cannot harvest them.

* `_stream_thread_run` now tracks `emitted_any` and refuses to fall
  through to the buffered `await thread.run(prompt)` after either
  streaming helper has already yielded text. Previously a network
  glitch mid-stream re-executed the same Codex turn, which can
  duplicate file writes, shell commands, and other Codex side
  effects. The buffered path is now reserved for the zero-output
  case (no streaming helper resolved, or streaming returned empty).

* `CodexLoginButton` now aborts the SSE reader on unmount via a
  useEffect cleanup that calls `abortRef.current?.abort()`. The
  underlying `codex login --device-auth` subprocess no longer
  keeps streaming (and holding a device-auth session) after the
  dialog closes.

Two new pytest cases pin the behaviour: `test_codex_subprocess_env_scrubbed`
sets HF/GH/WANDB/ANTHROPIC keys and asserts none reach the codex
env while OPENAI_API_KEY / CODEX_HOME survive; and
`test_partial_stream_failure_does_not_replay_turn` injects a fake
`turn().stream()` that yields "partial output " then raises, and
asserts `thread.run()` is never called. 28/28 codex_provider tests
pass; `tsc --noEmit` clean.
