gpuicn v0.9.1

gpuicn v0.9.1

Seven additions Matty asked for while building its chat client. Every change
is additive: existing code compiles and draws as before, and installed source
from v0.9.0 changes only in the files below (gpuicn diff lists them). The
runtime pins are unchanged: GPUI Kit 0.9.0 on gpui-pre 0.3.11 and gpui-icons
0.6.0.

Added

• Message: timestamp_tooltip shows the full date and time when the
  reader hovers the time, on header, continuation and compact rows (#94).
  on_gutter_click makes the avatar column a click target for selecting the
  row, while clicks on the body stay free for text selection and links (#98).
• Toast: Notice::action(label, handler) and Notice::cancel(label) add
  buttons to a notification. Pressing either dismisses it; the action runs its
  handler first. Tab reaches them before the close button, and hovering the
  stack pauses the timeout as before (#95).
• MessageList: on_jump hands the "Jump to latest" pill to the
  application, which can load the newest page after a jump into the past
  instead of scrolling to the loaded end. show_jump(true) keeps the pill
  visible at the loaded end of such a window (#97).
• Attachment: dimensions(width, height) sizes an image thumbnail from the
  file's metadata, keeping its aspect ratio inside max_size (360 × 240 by
  default), and holds that box with a muted fill while the image loads, so the
  transcript does not jump (#99).
• Sidebar: roving_focus(true) makes the navigation rows one tab stop.
  Tab lands on the focused or selected row and the next Tab leaves; Up and
  Down move between rows (wrapping, skipping disabled ones), Home and End jump
  to the ends, and the focused row scrolls into view (#100).
• Composer: ComposerState::set_max_rows and max_rows change the growth
  cap without rebuilding the state, and Composer::max_height(px) caps the
  text box in pixels, for example at 40% of the window, following resizes and
  keeping the draft (#101).
• ScrollArea: track_scroll(&ScrollHandle) shares the scroll position
  with the caller.
