FLVSTX 1.1.0

A redesigned editor, and a piano roll you can actually navigate.

Look and layout

• A shared navy and mint theme across the editor, a compact header, section cards, and instrument
  cards that preview their notes.
• Composition and playback controls are separated rather than sharing one bar; toolbars wrap and the
  sections and arrangement views scroll, so nothing is cut off at small window sizes.
• Larger controls throughout, and the restored UI scale now also applies to the piano-roll rows at
  startup rather than only after a change.

Piano roll

• Pan mode, middle-mouse panning, visible time and pitch scrollbars, and independent zoom for each
  axis. Navigation is bounded, and pitch rows stay aligned while scrolling.
• Notes are framed automatically when you switch section or layer, and are labelled; Fit notes
  resets both axes and uses the full grid width.
• Compact inline help instead of a wall of text.

Composer panel

• Collapsible, with a pinned message input, starter ideas, and quick actions you can edit before
  sending.
• Consecutive tool calls collapse into one expandable activity entry, and message roles and session
  updates read more clearly.

Fixes

• The standalone's delayed autosave could lose the final edit after a burst of changes.
• Stop now requests all-notes-off; Undo and Redo reflect the history that actually exists;
  alternative takes only appear for the layer they belong to.

Development

• A reproducible render of the real egui geometry, for visual QA of the editor.
