Codex CLI 0.148.0-alpha.5 changelog - what changed

[removed] Dropped the o1 model identifier from the built-in model list.
[changed] Expanded auto-review requirements configuration (additional fields on the requirements types).
[changed] Adjusted network-related environment flags (including removal of CODEX_SANDBOX_NETWORK_DISABLED and renames around the CODEX_NETWORK_* / cloud-tasks internal overrides).
[new] Added an AppReview data shape and agent-interrupt arguments for upcoming review/interrupt flows.
[changed] Hook handler configuration now distinguishes agent and MCP tool handlers more clearly.
[new] Collaboration sessions can emit a collab_waiting_end notification when a wait completes.
[removed] Removed the delete_to_line_end event and several unused payload/types (including guardian warning notification and token-usage profile leftovers).

Under the hood

Account/login and marketplace manifest enums were reshuffled (Bedrock/ChatGPT login paths and plugin source variants).
Web-search actions, wire content items, and parsed-command variants were tightened (e.g. find-in-page vs open-page, image input handling).
MCP elicitation and OpenTelemetry exporter kinds saw small renames/refactors aimed at clearer protocol and export options.
Minor typed-payload churn (DefaultConfig in, test-only sync args out) with no documented user-facing CLI changes in this bump.
