## [2026-05-14] Fix event logging: all mutating queries now logged in audit trail
### Problem
Two write paths bypassed the `LoggedTx` audit trail, causing `.events.jsonl`
to have no record of their mutations:
1. **`import_files.go` and `bulk_file_import.go`** passed `tx.UnderlyingTx()` to
   `utils.ImportCluster`, so all INSERTs inside `ImportCluster` bypassed the
   `LoggedTx` wrapper. The `LoggedTx` recorded 0 queries, so `Commit()` wrote
   no event.
2. **`utils.EnsureClusterPath`** did an UPDATE via `database.Exec()` on the raw
   `*sql.DB` outside any transaction — not logged, and not rolled back on failure.
### Fix
1. **Defined `Mutator` interface** in `utils/mutator.go` with `ExecContext` and
   `QueryRow` methods. Both `*sql.Tx` and `*db.LoggedTx` satisfy it. This avoids
   the import cycle that would result from `utils` importing `db`.

2. **Refactored `ImportCluster`** and its helpers (`insertClusterFiles`,
   `insertSingleFile`) to accept `Mutator` instead of `*sql.Tx`. Removed prepared
   statements (DuckDB Go driver doesn't benefit from them), using direct
   `ExecContext` calls instead.
3. **Moved `EnsureClusterPath` into transaction scope** in all callers
   (`import_file.go`, `import_files.go`, `bulk_file_import.go`). Changed it to
   accept `Mutator` and use `ExecContext` instead of `Exec`.
4. **Updated callers**: `import_files.go` and `bulk_file_import.go` now pass `tx`
   (LoggedTx, which satisfies Mutator) instead of `tx.UnderlyingTx()`.
5. **Deprecated `UnderlyingTx()`** with a warning comment.
6. **Reduced cyclomatic complexity** in `import_file.go` by extracting
   `insertNewFileRecord` helper (12 → 7).
7. **Added tests**:
   - `utils/mutator_test.go`: compile-time interface compliance
   - `db/tx_logger_test.go`: `TestLoggedTx_SatisfiesMutator`, `TestMutator_RecordsQueries`
   - `shell_scripts/test_event_log.sh`: comprehensive E2E test covering all mutating
     CLI commands (create, update, import file, import folder, import bulk, import
     unstructured, EnsureClusterPath logging)
### Files changed
- `utils/mutator.go` (new): Mutator interface definition
- `utils/mutator_test.go` (new): interface compliance tests
- `utils/cluster_import.go`: `*sql.Tx` → `Mutator`, removed prepared statements
- `utils/file_import.go`: `CheckDuplicateHash` accepts narrower interface
- `db/tx_logger.go`: compile-time `Mutator` check, deprecated `UnderlyingTx()`
- `db/tx_logger_test.go`: new Mutator-related tests
- `tools/import/import_files.go`: pass `tx` instead of `tx.UnderlyingTx()`,
  `EnsureClusterPath` inside transaction
- `tools/import/import_file.go`: `EnsureClusterPath` inside transaction,
  extracted `insertNewFileRecord`, commit on duplicate
- `tools/import/bulk_file_import.go`: pass `tx` instead of `tx.UnderlyingTx()`,
  `EnsureClusterPath` inside transaction
- `shell_scripts/test_event_log.sh`: rewritten for comprehensive coverage
