Codex CLI 0.146.0-alpha.10

• [changed] TUI turn handling is simplified by folding the separate chat turn-runtime path into the main chat flow.
• [removed] Dropped the exec_command_begin notification from the event surface as part of tightening runtime signaling.
• [changed] Internal escalate/follow-up wait plumbing is trimmed (related escalate socket override support and wait args are gone).
• [changed] Minor data-model and thread-store config shaping (including in-memory vs local thread store options) ahead of follow-on work.

Under the hood

• First-party source set shrinks slightly with the TUI turn-runtime module removal.
• Assorted typed payload and enum churn around approvals, marketplace plugin sources, scheduled tasks, and tool-call summaries—mostly structural cleanup rather than new CLI surface.
• Snapshot proxy override naming/env handling is adjusted in the binary surface; treat override configuration carefully if you relied on the prior variable spelling.
• Release metadata bumped to 0.146.0-alpha.10 / rust-v0.146.0-alpha.10.

Upgrade notes

• If you integrated against exec_command_begin or escalate-socket/EscalateFollowupWait-style APIs, expect those to be absent and adjust listeners accordingly.
• If you set a snapshot proxy override via environment, confirm the variable still matches what this build expects after the override env cleanup.
