The visible declaration already provides scope context. Cache the actual
identifier point separately from the declaration extent/decorators and hide
labels when it is visible in that side of the projected viewport.
Refill reclaimed rows and anchor carets against the resulting layout.
Retain sticky context when the symbol scrolls or wraps out of view.
Verified: 951 tests passed, cargo build, and real PTY smoke for declaration
visibility/scroll restoration, wrapping, horizontal clipping, unified view,
and short horizontal-pane caret reflow.
Show per-side Tree-sitter scope paths inline and as sticky continuation labels.
Keep presentation rows out of source coordinates, selections, and edits.
Verified: cargo test (949 passed), cargo build, and real PTY smoke covering
split/unified, wrapping, both split axes, sticky scrolling, live rename and undo.
Size exception: 549 implementation lines added plus deleted, excluding tests
and docs. Keep syntax extraction and coordinate-safe rendering together as one
working behavior.
