v1.1.0

Added

• Output panel: withOutput meta key plus a ---output--- separator splits a block into a
  highlighted command section and a plain-text output panel. Options: WithOutputPanel,
  WithOutputCollapsed, WithOutputSeparator (also available as outputPanel, outputDefaultCollapsed,
  outputSeparator in kazari.config.yaml).
• WithPostRender: register callbacks that post-process each block's HTML. Each receives the HTML
  and a BlockInfo (Lang, Title, Frame, RawCode, LineCount, Theme, Meta).
• Code annotations (@[text](url)) now show an external link icon and open in a new tab.

Changed

• not-content is now applied to every block unconditionally; it previously required
  WithContentExclusion.
• Scrollbars restyled with a thinner floating thumb. Override --kz-scrollbar-* to adjust.

Fixed

• Auto-collapse is suppressed when a line marker carries a label. Explicit collapse still wins.
• Per-block theme overrides: correct toolbar background, full chrome variable remapping, no more
  double-faded line numbers in alpha-color themes, and terminal backgrounds now respond to the toggle.
• An empty language string is treated as plaintext without a warning.
