viyatb-oai f276325cdc refactor: centralize filesystem permissions precedence (#14174)
## Stack

   fix: fail closed for unsupported split windows sandboxing #14172
   fix: preserve split filesystem semantics in linux sandbox #14173
   fix: align core approvals with split sandbox policies #14171
-> refactor: centralize filesystem permissions precedence #14174

## Summary
- add a shared per-path split filesystem precedence helper in
`FileSystemSandboxPolicy`
- derive readable, writable, and unreadable roots from the same
most-specific resolution rules
- add regression coverage for nested `write` / `read` / `none` carveouts
and legacy bridge enforcement detection

## Testing
- cargo test -p codex-protocol
- cargo clippy -p codex-protocol --tests -- -D warnings

codex-protocol

This crate defines the "types" for the protocol used by Codex CLI, which includes both "internal types" for communication between codex-core and codex-tui, as well as "external types" used with codex app-server.

This crate should have minimal dependencies.

Ideally, we should avoid "material business logic" in this crate, as we can always introduce Ext-style traits to add functionality to types in other crates.
