CODEX UNLOCKS EMPTY-INPUT TURNS, SHIPPING UNIFIED PACKAGE BUILD

Codex can now start real turns without user input, unblocking model reasoning from thread context alone.

The core blocker is gone: `turn/start` now accepts empty input arrays and lets them reach the model instead of short-circuiting [1]. This unblocks patterns where the model needs to proceed from existing conversation history without new user messages. Simultaneously, Codex is consolidating its release infrastructure [2] [4]. The CI pipeline now builds package archives directly from staged entrypoints, killing the rebuild step that made validation fragile. A new standalone package builder creates the canonical layout that npm staging, installers, and release bundles will converge on [4]. Supporting these changes, `EnvironmentManager` now treats local runtime paths as optional [3], simplifying how snapshot materialization works across different execution contexts. Finally, thread-spawned subagents gain their own lifecycle hook [5]: `SubagentStart` fires before the first model request, letting you match handlers on agent type and inject context specific to child agents.
