Changed #

• Terminal startup capability probing now queries DA2 as well as DA1, kitty keyboard, colors, and kitty graphics.
• Terminal startup capability probing now queries DA3 and terminal-version reports alongside the existing DA1/DA2, kitty keyboard, color, and kitty-graphics probes.
• Terminal startup capability probing now queries the terminal light/dark color-scheme report alongside the existing device, keyboard, graphics, and color probes.
• TerminalCapabilities now tracks exact kitty keyboard enhancement flags plus foreground, background, cursor, and palette color reports with idempotent updates.
• TerminalCapabilities now tracks ModifyOtherKeys mode reports and terminal dark/light color-scheme state instead of treating those reports as transient decode-only events.
• Terminal startup capability probing now queries foreground and cursor colors in addition to the existing background, keyboard, device-attribute, and kitty-graphics probes.
• TerminalCapabilities now infers Kitty and iTerm2 image-protocol support from terminal-version replies in addition to the existing environment and device-attribute hints.

Fixed #

• Terminal is now explicitly single-use after stop(), repeated mode toggles are idempotent, and changing kitty keyboard enhancement flags now resets the old mode before applying the new one.
• Added lifecycle coverage for kitty keyboard enhancement enable/disable behavior and shutdown cleanup in Terminal.
• Fixed capability state tracking so primary device attribute changes are detected even when Sixel support does not change, and repeated identical color/capability reports no longer churn state.
• TerminalCapabilities now stores and de-duplicates secondary device attributes instead of discarding DA2 reports after decode.
• TerminalCapabilities now stores and de-duplicates DA3 tertiary attributes and terminal-version reports instead of discarding them after decode.
• Added direct Terminal coverage for focus/blur events, bracketed paste events, and startup foreground/cursor color capability updates.
• Added direct Terminal coverage for mouse click, release, motion, and wheel events plus standard and in-band resize report handling.
• Added direct Terminal coverage for cursor-position, ModifyOtherKeys, and primary/secondary/tertiary device-attribute reports, including capability-state updates from DA1.
• Added direct Terminal coverage for clipboard, terminal-version, XTGETTCAP, background-color, and palette report handling.
• Fixed UvTerminalRenderer leading-blank overwrite fallback so it only emits blanks for truly blank old-line regions instead of using spaces to move across existing content.

• fix documentation + missing assets

Fixed #

• Updated package screenshots/readme media setup for pub.dev rendering.
• Added pubspec.yaml screenshot metadata (assets/layout.png) for package page preview.

Added #

• Layout/rendering helpers and example suite for advanced terminal graphics.

Fixed #

• Synchronized-output skipped-frame behavior in UvTerminalRenderer dirty-line handling.
