• [codex] Remove unused legacy shell tools (#22246)

  ## Why
  
  Recent session history showed no active use of the raw `shell`,
  `local_shell`, or `container.exec` execution surfaces. Keeping those
  handlers/specs wired into core leaves duplicate shell execution paths
  alongside the supported `shell_command` and unified exec tools.
  
  ## What changed
  
  - Removed the raw `shell` handler/spec and its `ShellToolCallParams`
  protocol helper.
  - Removed the legacy `local_shell` and `container.exec` handler/spec
  plumbing while preserving persisted-history compatibility for old
  response items.
  - Normalized model/config `default` and `local` shell selections to
  `shell_command`.
  - Pruned tests that exercised removed raw-shell/local-shell/apply-patch
  variants and kept coverage on `shell_command`, unified exec, and
  freeform `apply_patch`.
  
  ## Verification
  
  - `git diff --check`
  - `cargo test -p codex-protocol`
  - `cargo test -p codex-tools`
  - `cargo test -p codex-core tools::handlers::shell`
  - `cargo test -p codex-core tools::spec`

• feat: extract shared tool executor interface (#22359)

  ## Why
  
  Codex still models model-visible tools and executable behavior largely
  inside `codex-core`, which makes it harder to evolve the tool system
  toward a single reusable abstraction for built-ins, MCP-backed tools,
  dynamic tools, and later tools injected from outside core.
  
  This PR takes the next incremental step in that direction by moving the
  common execution-facing pieces out of core and separating them from
  core-only orchestration. The intent is to let shared tool abstractions
  improve in one place, while `codex-core` keeps the parts that are still
  inherently host-specific today, such as `ToolInvocation`, dispatch
  wiring, and hook integration.
  
  This PR is mostly moving things around. The only interesting piece is
  this abstraction:
  https://github.com/openai/codex/pull/22359/changes#diff-81af519002548ba51ed102bdaaf77e081d40a1e73a6e5f9b104bbbc96a6f1b3dR13
  
  ## What changed
  
  - Added `codex_tools::ToolExecutor<Invocation>` as the shared execution
  trait for model-visible tools.
  - Moved the reusable execution support types from `codex-core` into
  `codex-tools`:
    - `FunctionCallError`
    - `ToolPayload`
    - `ToolOutput`
  - Refactored core tool implementations so that execution behavior lives
  on `ToolExecutor<ToolInvocation>`, while `ToolHandler` remains the
  core-local extension point for hook payloads, telemetry tags, diff
  consumers, and other orchestration concerns.
  - Kept the registry and dispatch flow behaviorally unchanged while
  making the shared/extracted boundary explicit across built-in, MCP,
  dynamic, extension-backed, shell, and multi-agent tool handlers.
  
  ## Verification
  
  - `cargo test -p codex-tools`
  - `just fix -p codex-tools`
  - `just fix -p codex-core`
  - `cargo test -p codex-core` progressed through the updated tool
  surfaces and then hit the existing unrelated multi-agent stack overflow
  in
  `tools::handlers::multi_agents::tests::tool_handlers_cascade_close_and_resume_and_keep_explicitly_closed_subtrees_closed`.
