feat(permissions): voie projection CLI (LP0→LP3) + checkpoint Codex/input

Jalon vert regroupant deux chantiers entrelacés dans le working tree,
indissociables au niveau fichier mais tous deux verts (cargo test
--workspace + tests frontend permissions au vert).

Permissions — voie « projection CLI » (advisory), complète :
- LP0 domaine pur : modèle PermissionSet/EffectivePermissions, resolve
  deny-wins + postures Allow<Ask<Deny (crates/domain/src/permission.rs).
- LP1 store : FsPermissionStore (.ideai/permissions.json).
- LP2 use cases : Get/Update project, Update agent override, Resolve.
- LP3 projecteurs Claude/Codex (settings.local.json / config.toml),
  câblage launch-path + PermissionProjectorRegistry, nettoyage des
  fichiers Replace orphelins au swap de profil (LP3-4), composition root
  + commandes Tauri, UI PermissionsPanel (projet + override agent).
- ports.rs : PermissionStore + FileSystem::remove_file (cleanup au swap).

Reste ouvert (hors scope, marqué dans le code) : LP4 enforcement OS
airtight (Landlock fichiers) + résumé de permissions injecté.

Inclut aussi le chantier Codex/input/sessions structurées en cours
(McpConfigStrategy, StructuredAdapter, gestion d'input) partageant les
mêmes fichiers (lifecycle.rs, commands.rs, dto.rs, state.rs).

//! Codex CLI permission projector (lot LP3-2).
//!
//! Produces the **permission-relevant** part of Codex's `config.toml`
//! (`sandbox_mode` / `approval_policy`) plus the matching launch args
//! (`--sandbox` / `--ask-for-approval`). The posture→mode derivation is extracted
//! verbatim from the former `codex_sandbox_mode` / `codex_approval_policy` /
//! `apply_codex_cli_permission_args` in `lifecycle.rs`.
//!
//! Unlike Claude's seed, Codex's `config.toml` is **co-owned** (it also carries the
//! `mcp_servers.idea` table and the `projects.*` trust entries, which are MCP/trust
//! concerns, not permissions). The projector therefore emits a
//! [`ProjectedFile::MergeToml`] limited to the two permission keys it manages —
//! everything else in the file is preserved by the fold, and the file is **never**
//! deleted on swap (hence an empty `owned_replace_paths`).
