app-server: accept command permission profiles (#18283)

## Why

`command/exec` is another app-server entry point that can run under
caller-provided permissions. It needs to accept `PermissionProfile`
directly so command execution is not left behind on `SandboxPolicy`
while thread APIs move forward.

Command-level profiles also need to preserve the semantics clients
expect from profile-relative paths. `:cwd` and cwd-relative deny globs
should be anchored to the resolved command cwd for a command-specific
profile, while configured deny-read restrictions such as `**/*.env =
none` still need to be enforced because they can come from config or
requirements rather than the command override itself.

## What Changed

This adds `permissionProfile` to `CommandExecParams`, rejects requests
that combine it with `sandboxPolicy`, and converts accepted profiles
into the runtime filesystem/network permissions used for command
execution.

When a command supplies a profile, the app-server resolves that profile
against the command cwd instead of the thread/server cwd. It also
preserves configured deny-read entries and `globScanMaxDepth` on the
effective filesystem policy so one-off command overrides cannot drop
those read protections. The PR also updates app-server docs/schema
fixtures and adds command-exec coverage for accepted, rejected,
cwd-scoped, and deny-read-preserving profile paths.

## Verification

- `cargo test -p codex-app-server
command_exec_permission_profile_cwd_uses_command_cwd`
- `cargo test -p codex-app-server
command_profile_preserves_configured_deny_read_restrictions`
- `cargo test -p codex-app-server
command_exec_accepts_permission_profile`
- `cargo test -p codex-app-server
command_exec_rejects_sandbox_policy_with_permission_profile`
- `just fix -p codex-app-server`

- For clients that are already sandboxed externally, set `sandboxPolicy` to `{"type":"externalSandbox","networkAccess":"enabled"}` (or omit `networkAccess` to keep it restricted). Codex will not enforce its own sandbox in this mode; it tells the model it has full file-system access and passes the `networkAccess` state through `environment_context`.
- For clients that are already sandboxed externally, set the legacy `sandboxPolicy` to `{"type":"externalSandbox","networkAccess":"enabled"}` (or omit `networkAccess` to keep it restricted). Codex will not enforce its own sandbox in this mode; it tells the model it has full file-system access and passes the `networkAccess` state through `environment_context`.
Notes:
- Empty `command` arrays are rejected.
- `sandboxPolicy` accepts the same shape used by `turn/start` (e.g., `dangerFullAccess`, `readOnly`, `workspaceWrite` with flags, `externalSandbox` with `networkAccess` `restricted|enabled`).
- Prefer `permissionProfile` for command permission overrides. The legacy `sandboxPolicy` field accepts the same shape used by `turn/start` (e.g., `dangerFullAccess`, `readOnly`, `workspaceWrite` with flags, `externalSandbox` with `networkAccess` `restricted|enabled`), but cannot be combined with `permissionProfile`.
- `env` merges into the environment produced by the server's shell environment policy. Matching names are overridden; unspecified variables are left intact.
- When omitted, `timeoutMs` falls back to the server default.
- When omitted, `outputBytesCap` falls back to the server default of 1 MiB per stream.
