Builds out host-drawn text selection for embedded napplet/nsite/browser surfaces toward native parity, and fixes the bugs found while exercising it. - Magnifier loupe (#4): EmbeddedMagnifier + provider-side pixel capture (EmbeddedMagnifierProbe) shipped over IPC for both embed paths; the caret/selection handles drive it via OnMagnify. - SelectionUiState: single source of truth for the overlay show/hide rules (insertion caret / in-field range / page-text range + dragging/scrolling). - EmbeddedSelectionDrag: suspends the nav drawer's edge swipe while a handle is dragged (auto-scroll #9). Bug fixes: - No more overlay blink on word-select: the shim's selection-reveal scrolls (a textarea auto-scrolling to show a forming/re-asserted range) no longer trip the hide-on-scroll path, and the hide self-heals instead of being re-armed indefinitely. - RemoteImeView debounces the range-lost signal so a transient collapse that gets re-asserted doesn't flicker the handles/toolbar. - Focusing a field clears any page-text selection (shim + host), so the stale page handles/Copy bar no longer linger above — and stop stealing drags from — the field overlays; also cancels any in-flight scroll-hide on focus. - Caret insertion-handle drag now actually moves the caret: read the pointer delta with positionChangeIgnoreConsumed() before consuming, so the value isn't zeroed by our own consume (or the sandbox surface consuming the move).
