• [connectors] Support connectors part 1 - App server & MCP (#9667)

  In order to make Codex work with connectors, we add a built-in gateway
  MCP that acts as a transparent proxy between the client and the
  connectors. The gateway MCP collects actions that are accessible to the
  user and sends them down to the user, when a connector action is chosen
  to be called, the client invokes the action through the gateway MCP as
  well.
  
   - [x] Add the system built-in gateway MCP to list and run connectors.
   - [x] Add the app server methods and protocol

• feat(tui): retire the tui2 experiment (#9640)

  ## Summary
  - Retire the experimental TUI2 implementation and its feature flag.
  - Remove TUI2-only config/schema/docs so the CLI stays on the
  terminal-native path.
  - Keep docs aligned with the legacy TUI while we focus on redraw-based
  improvements.
  
  ## Customer impact
  - Retires the TUI2 experiment and keeps Codex on the proven
  terminal-native UI while we invest in redraw-based improvements to the
  existing experience.
  
  ## Migration / compatibility
  - If you previously set tui2-related options in config.toml, they are
  now ignored and Codex continues using the existing terminal-native TUI
  (no action required).
  
  ## Context
  - What worked: a transcript-owned viewport delivered excellent resize
  rewrap and high-fidelity copy (especially for code).
  - Why stop: making that experience feel fully native across the
  environment matrix (terminal emulator, OS, input modality, multiplexer,
  font/theme, alt-screen behavior) creates a combinatorial explosion of
  edge cases.
  - What next: we are focusing on redraw-based improvements to the
  existing terminal-native TUI so scrolling, selection, and copy remain
  native while resize/redraw correctness improves.
  
  ## Testing
  - just write-config-schema
  - just fmt
  - cargo clippy --fix --all-features --tests --allow-dirty --allow-no-vcs

  - cargo clippy --fix --all-features --tests --allow-dirty --allow-no-vcs

• feat: publish config schema on release (#9572)

  Follow up to #8956; publish schema on new release to stable URL.
  
  Also canonicalize schema (sort keys) when writing. This avoids reliance
  on default `schema_rs` behavior and makes the schema easier to read.

• feat(personality) introduce model_personality config (#9459)

  ## Summary
  Introduces the concept of a config model_personality. I would consider
  this an MVP for testing out the feature. There are a number of
  follow-ups to this PR:
  
  - More sophisticated templating with validation
  - In-product experience to manage this
  
  ## Testing
  - [x] Testing locally

• add WebSearchMode enum (#9216)

  ### What
  Add `WebSearchMode` enum (disabled, cached live, defaults to cached) to
  config + V2 protocol. This enum takes precedence over legacy flags:
  `web_search_cached`, `web_search_request`, and `tools.web_search`.
  
  Keep `--search` as live.
  
  ### Tests
  Added tests

• add generated jsonschema for config.toml (#8956)

  ### What
  Add JSON Schema generation for `config.toml`, with checked‑in
  `docs/config.schema.json`. We can move the schema elsewhere if preferred
  (and host it if there's demand).
  
  Add fixture test to prevent drift and `just write-config-schema` to
  regenerate on schema changes.
  
  Generate MCP config schema from `RawMcpServerConfig` instead of
  `McpServerConfig` because that is the runtime type used for
  deserialization.
  
  Populate feature flag values into generated schema so they can be
  autocompleted.
  
  ### Tests
  Added tests + regenerate script to prevent drift. Tested autocompletions
  using generated jsonschema locally with Even Better TOML.
