`prepareGeometryChange()` ran after the gap rects and arrow specs
were mutated. Qt could retain the item's old scene index even
though `boundingRect()` returned its new prepended-history
position.
Invalidate cached bounds and notify Qt before changing any
geometry. Cover both scene lookup positions with a real offscreen
item.

`PlotItem.addItem()` records overlays outside the Qt scene. Direct
scene removal leaves stale plot refs and range bookkeeping behind.
Track each annotation's owning plot and remove it through the same
API used for insertion. Exclude pixel-sized arrows from data
bounds.
Deats,
- centralize replacement, hiding and owner teardown;
- retain scene removal as a defensive fallback;
- cover real Qt registries and duplicate-FQME chart identity.

Detect positive timestamp gaps from chart OHLCV SHM with one
vectorized pass. Route local UI and remote callers through one
`GapOverlayMngr` renderer, and key each layer by owner, chart,
FQME and timeframe so remote ctx teardown cannot remove local
graphics.
Deats,
- add tagged `SetGapOverlay` requests and typed
`GapOverlay` responses;
- keep `remote_annotate()` intact and serve its typed dialog from
a dedicated `remote_gap_overlays()` Tractor ctx;
- admit `SetGapOverlay`, `GapOverlay`, `list[str]` and `None` in
the Tractor payload spec, then strictly narrow requests to
`SetGapOverlay` and replies to `GapOverlay`;
- serialize shared-stream dialogs and correlate request IDs so
stale replies cannot skew later exchanges;
- rename `AnnotCtl` / `open_annot_ctl()` to `AnnotClient` /
`open_annot_client()` across storage and annotation callers;
- enable 60s history overlays at startup and toggle the focused
1s or 60s chart directly with `Ctrl+G`;
- guard redraws by chart, FQME and timeframe; tolerate empty
arrays and out-of-range lookups; update rect and arrow geometry;
- cover detector geometry, msgpack roundtrips, schema rejection,
typed stale-FQME errors and renamed storage seams;
- document ownership, refresh, stack landing and live
qualification.
