Navi Code TUI: fix Phase 4 review critical/medium issues ...

- PermissionEngine: always-deny returns None via check(); is_always_deny() exposed for explicit rejection; default rules for code_exec/ssh_exec/shell; extract_target() made public.
- ShellRunner: set ShellResult.truncated when output is actually truncated.
- File refs: restrict paths to base_dir/home, block sensitive files/dirs, skip binary, support glob brackets, shared guess_language.
- Permission dialog: deny now renders synthetic tool_call before stopping; shell ! commands require permission with always-allow/deny persistence.
- Tests: add permission tests, fix file_refs/shell tests, add __init__.py to fix pytest name collisions, update websocket integration for AgentSessionOrchestrator.

504 passed, 1 skipped. Ruff clean.
