Codex CLI 0.153.0-alpha.6

• [changed] Thread identity is now taken from CODEX_THREAD_ID (replacing the prior CODEX_THREAD_IDT name).
• [removed] The CODEX_SANDBOX_NETWORK_DISABLED environment variable is no longer recognized.
• [changed] TUI Vim normal-mode keybindings were extended and reworked.
• [changed] Hook configuration now centers on MCP tool hooks instead of command-style hook handlers.
• [changed] Client protocol events use an ack-style result path in place of the previous client-message result event.
• [new] A mitm_hook_denied notification is emitted when a MITM hook blocks an action.
• [removed] The collab_waiting_end event is gone.
• [changed] Amazon Bedrock login/setup parameter shapes were updated (including access-key oriented setup).
• [changed] Tool-call summarization and several filesystem path variants were refined (terminal-oriented summaries; glob-pattern exec paths).
• [changed] Collaboration/waiting and several plugin/app discovery response shapes were dropped or replaced as the workspace and marketplace message models moved forward (including patch-approval and turn-steer responses).

Under the hood

• Workspace messaging and marketplace interface types were introduced; older apps-installed, capability-roots, plugin hook/share, and skill-dependency response models were removed.
• MCP elicitation payload typing and tool-trace/dispatch response variants were adjusted (including correlation and direct-response paths).
• Delegate request and dynamic tool output item variants were reshuffled as part of the same protocol cleanup.
• Cargo.lock and release metadata were bumped for 0.153.0-alpha.6.
