docs: refresh schema/architecture/description/troubleshooting Subagent stale-plan audit against the post-launch codebase. Four docs drifted across the May→June migration cycle: - database_schema.md: bumped migration count (12 → 18); added Schema Evolution rows for M013–M018; added samples.source_path, collections.filter_json, sync_state.row_id_salt; removed smart_folders block (dropped in M015); noted that sync_changelog.row_id is hashed for sensitive tables (M018). - architecture.md: bumped migration count; swapped smart_folders row for edit_history in the schema table; mentioned row_id hashing + canonical PK in encrypted data; updated import-extension list to wav/aiff/aif/mp3/flac/ogg/m4a/alac/caf/bwf; noted atomic export writes via write_atomic. - description.md: replaced "Smart Folders" feature block with "Dynamic Collections" (filter_json); added Cmd+I / Cmd+, About shortcut; fixed supported-extension list. - troubleshooting.md: migration count; sync-table list including edit_history + user_config; row_id_salt cautionary note; fixed wrong mirror path (~/.audiofiles-mirror → ~/audiofiles-mirror). design-system.md, loose-files-mode.md, ml_classifier.md, plugin_authoring.md, trial-mode.md graded CURRENT; left alone.

Progress is reported per file. Each output is written atomically via a `write_atomic(dest, |tmp| ...)` helper — the encoder/copier targets `dest.audiofiles_tmp`, then `fs::rename`s into place on success. A killed export never leaves a partial file in the user's export directory.
