NiceGUI's ui.image with a local file path fails to register static
files when inside a ui.dialog, showing alt text instead of the image.
Added /api/image-preview?path=... endpoint that streams the file via
FileResponse, and updated frame path thumbnails to use this URL.

Removed end_frame mirror. Logic index is now entirely computed
from the 3 frame switches (bit 0=start, bit 1=middle, bit 2=end).

Quasar tooltip size constraints prevent large images from rendering.
Thumbnail is now clickable (cursor:pointer) and opens a full-size dialog.

Each frame path row (start/middle/end) now has:
- path input with preview
- strength float (default 1.0)
- switch linked to the corresponding logic index bit
Switches and logic index are bidirectionally synced.
end_frame → logic index → switches mirror chain preserved.

Bit 0 = start frame, bit 1 = middle frame, bit 2 = end frame.
Tooltip shows the full 0-7 truth table on hover.

direction:rtl caused path characters to render in wrong order.
text-align:right right-aligns the text (shows end of path) without
breaking the character display order.

Temporary field to ease node migration. Initializes to end_frame's
value and stays in sync whenever end_frame changes.

Updates DEFAULTS, standard_keys, UI label, and timeline known_keys.
Adds _migrate_key_renames() called on load_json to auto-migrate
existing JSON files with the old key name.

commit() is async but was called without await from sync handlers
(clone_next, clone_end, clone_sub, delete, copy_source, del_custom,
add_param, _sync_entry, _randomize) — causing saves and UI refreshes
to silently never run. Made all handlers async and added await.
Also fixed for i,entry loop shadowing the card's i parameter,
which was causing _render_vace_settings to receive the wrong index.
Removed unawaited render-time commit() in resolutions init block.

Replace HistoryTree (DAG with branches, Graphviz rendering) with a flat
chronological SnapshotTimeline. New UI features: split-view layout,
snapshot compare/diff, cherry-pick restore of individual sequences or
fields, auto-snapshots with debounce, and pin/filter support.

Reverses the previous merge migration. Lora data is now stored as
separate keys: 'lora 1 high' (STRING name) and 'lora 1 high strength'
(FLOAT). This allows ProjectKey relay nodes to output name and strength
as properly typed separate values.

The JSON file was storing full snapshot data in every history node,
causing files to grow to multi-GB. Now when DB is enabled:
- sync_to_db receives full tree (extracts snapshots to DB)
- save_json receives slim tree (no snapshot data)
- JSON file stays small, DB is authoritative for snapshots
When DB is disabled, JSON still stores full snapshots (only store).

- _auto_change_note now loads previous snapshot from DB instead of
reading stripped in-memory node (was producing wrong commit messages)
- _render_mass_update now strips snapshots after save (was leaking RAM)
- Only strip snapshots when DB is enabled (preview/restore still works
without DB via in-memory or disk fallback)
- _render_data_preview adds disk fallback matching _restore_node

History tree nodes stored full data snapshots in memory (5-50MB each),
accumulating with every save. Now:
- New `history_snapshots` DB table stores node data separately
- `save_history_tree` and `sync_to_db` extract snapshots before saving
- In-memory tree nodes only hold metadata (id, parent, note, timestamp)
- Restore and preview load snapshots from DB on demand
- `save_and_snap` uses json roundtrip instead of deepcopy (1 copy not 2)
- `_src_cache` moved to AppState, cleared on file switch
- `strip_snapshots()` method on HistoryTree for explicit cleanup

json.dump in a background thread would crash with "dictionary changed
size during iteration" when the UI mutated data concurrently. Now all
save_json and sync_to_db calls receive a json.loads(json.dumps(data))
snapshot, isolating the serialization from live UI mutations.

- load_file and on_select try db.load_full_data first (~0.01s),
fall back to load_json only when DB has no data
- Fix unawaited coroutine warning for auto-load (asyncio.ensure_future)
- Fix radio on_change to properly await async load_file
- Reuse current data cache when source file matches current file,
eliminating a redundant 1.3s JSON parse during render

Combines separate lora name and strength keys into "name:strength" format,
removing 6 strength keys to free output slots for mode. Migration handles
legacy <lora:> wrapper, separate strength keys, and already-merged formats.

Store lora name and strength as independent JSON keys instead of the
combined <lora:name:strength> format. Legacy format is auto-migrated

Root cause: save_json + sync_to_db blocked the event loop while
serializing the growing history tree (all snapshots) as JSON,
causing NiceGUI websocket timeout and client reconnect.
- Skip history tree in snapshot deepcopy (copied only to discard)
- Move save_json/sync_to_db to asyncio.to_thread in all callbacks
- Make save_and_snap, commit, sort_by_number, shift_fts,
_add_sequence, apply_mass_update async
