drawRectsImageContent's modern path computed nextRadius and
prevRadius as min(outerRadius, floor(|Δx| * 0.5)). When |Δx| < 2
the floor produces 0 and the addArc call becomes a no-op,
leaving an unsmoothed corner at the stair-step. Replace floor
with ceil so any non-zero edge mismatch rounds up to at least
1 px. Exact-equality cases (Δx == 0) are unaffected — they take
the else branch with a straight addLine.

In drawRectsImageContent's modern path the snap loop runs midY
trimming first, leaving rects[i].maxY == rects[i+1].minY for
adjacent line rects. The X-edge snap guard then evaluated
rects[i].insetBy(dx: 0.0, dy: 1.0).intersects(rects[i+1]) — but
positive dy shrinks the rect, so after the trim the guarded
rectangle no longer intersects its neighbor (CGRect.intersects
requires positive-area overlap). Flip dy to -1.0 so the temp
rect grows and touching neighbors satisfy the guard.

Plan covers two single-line edits in LinkHighlightingNode.swift's
modern branch (X-snap dy direction; floor → ceil for stair-step
fillet radii), each landed as its own commit, with a final
full-project build for validation since this repo has no tests.

Document the analysis and intended fixes for two bugs in
LinkHighlightingNode's modern path branch: the X-edge snap is
unreachable after the midY snap (positive dy in insetBy shrinks
rect[i] so it can't intersect the touching neighbor), and the
floor() in nextRadius/prevRadius can produce zero-radius arcs.

drawInTile previously stroked each cell's full perimeter, double-drawing
every interior gridline; visible now that the rich-data chat bubble uses
tableBorderColor at 0.25 alpha. Stroking each segment in its own
strokePath call would also have left ~1pt² overdraw at every interior
4-cell junction (where a horizontal divider crosses a vertical one) and
at every T-junction with the outer rounded rect — each strokePath
rasterizes independently and composites against the previous result.
Build a single CGMutablePath containing each cell's interior top/left
segment (skipping cells on the table's top/left boundary) plus the outer
rounded perimeter rect, and call strokePath once. CGContextStrokePath
fills the union of all stroke geometries as a single fill op, so each
pixel is painted exactly once regardless of how many segments overlap.
Empty cells (text == nil) are no longer skipped wholesale: their fill
and text remain gated on text != nil (preserves today's no-fill-for-
empty behavior), but their interior divider segments still get appended
so divider continuity is preserved around them.

Adds drag-handle text selection driven by TextSelectionNode. Exposes
attributedString and selection helpers on InstantPage text items, and
introduces a multi-text adapter aggregating items as a TextNodeProtocol.
Gates selection actions on reply-options and fixes highlight z-order.
Adds a base getAnchorRect on ChatMessageBubbleContentNode, the rich-bubble
override (including titleHeight in details recursion), bubble-item
forwarding to content nodes, ChatControllerInteraction.scrollToMessageIdWithAnchor,
and a scrollToAnchor that lands the anchor at the top of the content area /
its line. Threads anchor/scroll params through ChatController and related
call sites.
Documents a two-pass refactor for InstantPageTableItem.drawInTile that
draws each interior divider exactly once (top+left of each cell that
isn't on the table boundary) plus a single rounded-rect outer-perimeter
stroke. Needed now that tableBorderColor is being made semi-transparent
(0.25 alpha) by the rich-data chat bubble; current per-cell whole-bounds
strokes overdraw shared edges.

Adds ChatControllerInteraction dependency, link-progress state, URL tap
detection, press-highlight separation from in-flight URL shimmer, media-tap
routing through openMessage with explicit IV media subject, and gallery↔bubble
transition with hidden-media coordination. Stops re-appending to
currentLayoutItemsWithNodes across re-layouts. Drops a leftover MetalEngine
debug print as well.
When a pinToEdgeWithInset item is taller than half of the visible
area (visibleSize.height - insets.top - insets.bottom), cap its
visible portion at halfArea. The remaining height extends past
visibleSize - insets.bottom into the bottom-inset region (occluded
by overlay UI like the chat input panel).
A new private helper `pinToEdgeBottomExtension(forPinnedHeight:)`
returns max(0, pinnedHeight - halfArea). Three sites consume it:
- calculatePinToEdgeTopInset caps the pinned item's contribution
to totalAboveAndPinned via `pinnedHeight - extension`.
- replayOperations isPinToEdgeTarget anchors the pinned item's
apparent maxY at visibleSize - insets.bottom + extension.
- isStrictlyScrolledToPinToEdgeItem matches the new anchor.
Both isPinToEdgeTarget and isStrictlyScrolledToPinToEdgeItem fire
when either calculatePinToEdgeTopInset() > 0 OR extension > 0, so
the cap also applies when items above the pinned item overflow
the visible area (in which case calculatePinToEdgeTopInset returns
0 but extension is still positive).
When the pinned item fits within halfArea, extension == 0 and
behavior is identical to before this change.
