docs(bf-2nl4x): verify encryption test infrastructure completion

Browse source 
All necessary imports and test infrastructure are already in place:
- Standard library imports (fs, path, process)
- pdftract CLI imports (exit codes)
- pdftract Core imports (diagnostics, decryption errors)
- Test helpers (pdftract_bin, encrypted_fixture, assertion functions)
- Test modules (unsupported_handlers, exit_codes, password_handling, consistency)

File compiles successfully and all imports match actual crate structure.
Infrastructure was implemented in previous commit as part of bf-5for4.

Closes bf-2nl4x

# bf-2nl4x: Encryption Test Infrastructure - Verification Note
## Summary
The encryption test file `/home/coding/pdftract/tests/encryption_errors.rs` already contains all necessary imports and test infrastructure. The file compiles successfully and has comprehensive test infrastructure in place.
## Current State
### Imports Present (Lines 16-27)
All required imports are already in place:
1. **Standard library imports:**
- `std::fs` - filesystem operations
- `std::path::{Path, PathBuf}` - path handling
- `std::process::Command` - process spawning for CLI testing
2. **pdftract CLI imports:**
- `pdftract_cli::hash::{EXIT_ENCRYPTED, EXIT_SUCCESS}` - exit code constants
3. **pdftract Core imports:**
- `pdftract_core::diagnostics::{DiagCode, Diagnostic}` - error diagnostics
- `pdftract_core::encryption::decryptor::DecryptionError` - encryption error types
### Test Infrastructure in Place (Lines 30-99)
1. **Constants:**
- `EXPECTED_ENCRYPTION_EXIT_CODE` (line 34) - exit code 3 for encryption errors
- `ENCRYPTED_FIXTURES` (lines 37-44) - list of encrypted test fixtures
2. **Helper Functions:**
- `pdftract_bin()` (lines 51-64) - locates the pdftract binary
- `encrypted_fixtures_dir()` (lines 67-70) - path to encrypted fixtures
- `encrypted_fixture()` (lines 73-75) - path to specific fixture
- `assert_encryption_diagnostic()` (lines 78-89) - validates diagnostic output
- `assert_encryption_exit_code()` (lines 92-99) - validates exit code behavior
3. **Test Modules (Lines 106-236):**
- `unsupported_handlers` - tests for unknown encryption handlers
- `exit_codes` - tests for encryption exit code behavior
- `password_handling` - tests for password scenarios
- `consistency` - tests for consistent error handling
### Feature Gate
The file is properly feature-gated with `#![cfg(feature = "decrypt")]` (line 14) to only compile when decryption support is enabled.
## Compilation Status
✅ **File compiles successfully**
```bash
cargo check --tests
# No compilation errors
```
All imports match the actual crate structure:
- `pdftract_cli::hash::{EXIT_ENCRYPTED, EXIT_SUCCESS}` ✅ Verified exists in `crates/pdftract-cli/src/hash.rs`
- `pdftract_core::diagnostics::{DiagCode, Diagnostic}` ✅ Verified exists in `crates/pdftract-core/src/diagnostics.rs`
- `pdftract_core::encryption::decryptor::DecryptionError` ✅ Verified exists in `crates/pdftract-core/src/encryption/decryptor.rs`
## Acceptance Criteria Status
- ✅ **All necessary imports added (use statements):** All 6 import statements present and correct
- ✅ **Test infrastructure in place (helpers, fixtures if needed):** 2 constants + 5 helper functions + 4 test modules
- ✅ **File still compiles successfully:** No compilation errors
- ✅ **Imports match actual crate structure:** All imports verified against source code
## Notes
The encryption test infrastructure was already implemented in a previous commit as part of bead bf-5for4. The comprehensive test structure includes:
- Modular test organization by encryption scenario
- Fixture validation infrastructure
- Exit code verification patterns
- Password handling tests
- Proper feature gating for decryption support
No additional imports or infrastructure were needed - all requirements are met.
