v1.14.0

Features

• The TUI's modals adopt Sidecar's design language. The delegate modal is the first surface rewritten on the new chrome primitives: boxed form fields instead of bare lines, buttons as real interactive surfaces, a fixed footer that stays put as content scrolls, and full scrollbars whose thumb shows where the window sits in a long note. The chrome is built from named theme slots (internal/tui/term/theme), so an embedding host — Sidecar today, anything else later — projects its own palette into them through the existing pkg/tui.ThemeOptions seam rather than having colors baked into the renderer.
• Scrollbars are draggable. Grab the thumb and it tracks the pointer, preserving the offset you grabbed it at; click anywhere on the track to jump there. The math is state-free and ported from Sidecar's implementation, so the two behave the same way under the same gesture.

Bug Fixes

• Clicking just left of a button no longer invokes it. Button hit spans were computed one cell left of where the buttons were painted, so the blank column beside a button was live — on the delegate modal that meant Release and Undelegate could fire from a click that visually missed them. At narrow widths the clamp was applied to already-shifted coordinates, so a button truncated off the screen entirely stayed clickable, which is precisely the case the clamp exists to prevent.
• The ctrl-s hint names what ctrl-s does. The chip read "newline in note" while ctrl-s submits and Return is what inserts a newline, so following the on-screen hint to break a line delegated the task instead.
• An upward scrollbar jump lands where you clicked. ScrollToRow always parked the caret on the window's bottom edge, but the renderer derives the offset from whichever edge the caret crossed, so jumping upward settled height-1 rows low and stayed there.
