Michael Bolin dcec516313 protocol: canonicalize file system permissions (#18274)
## Why

`PermissionProfile` needs stable, canonical file-system semantics before
it can become the primary runtime permissions abstraction. Without a
canonical form, callers have to keep re-deriving legacy sandbox maps and
profile comparisons remain lossy or order-dependent.

## What changed

This adds canonicalization helpers for `FileSystemPermissions` and
`PermissionProfile`, expands special paths into explicit sandbox
entries, and updates permission request/conversion paths to consume
those canonical entries. It also tightens the legacy bridge so root-wide
write profiles with narrower carveouts are not silently projected as
full-disk legacy access.

## Verification

- `cargo test -p codex-protocol
root_write_with_read_only_child_is_not_full_disk_write -- --nocapture`
- `cargo test -p codex-sandboxing permission -- --nocapture`
- `cargo test -p codex-tui permissions -- --nocapture`
