Markdown holds its parsed tokens weakly: a token tree is about ten times its
source, and every transcript message keeps a Markdown component. The tokens
still survive bursts of re-renders such as theme previews. Markdown, Text, and
Box flatten their cached lines, which V8 otherwise keeps as trees of the
concatenated parts. A long assistant message keeps about a fifth of the heap.
Adds fullscreenWheelScrollLines ("auto" or 1-100). Auto keeps one line
per event in local macOS terminals and scales with wheel velocity
elsewhere, capped at six lines per event.

Theme previews re-render the whole transcript, and streaming re-renders
every frame, so per-line and per-session work dominated in long sessions.
- visibleWidth: fast path for ANSI-styled ASCII, allocation-free escape scanning
- Box: compare unpadded child lines and skip a second width measurement
- Markdown: reuse parsed tokens across invalidation
- footer: cache usage totals and context usage per session state
- bash results: cache the collapsed preview including the expand hint
- sanitizeBinaryOutput: single regex replace
Read Finder file URLs before icon image data on macOS. Quote paths in
bash mode and reject terminal control characters before rendering.
Fixes#9999

* feat(coding-agent,tui): add system theme derived from terminal colors
The new default system theme builds pi's colors from the terminal's reported foreground, background, and ANSI palette. Tokens take their hue and relative saturation from a palette slot; lightness is placed by OKLab lightness difference and WCAG 2 contrast minimums. Terminals that report only a background get built-in hues, and terminals that report nothing get ANSI indices with faint secondary text.
The TUI queries OSC 10, 11, and 4 in one burst ended by DA1, so replies complete in one round trip, and reports replies that arrive after the timeout. Startup never waits: the system theme starts in grayscale and updates when colors arrive. Light/dark detection now uses the reported colors instead of the ?996 query; mode 2031 notifications trigger a new query.
* fix(coding-agent): wait for terminal colors before building the startup header
The header and startup notices bake theme colors into their text. When the color replies arrived after they were built, as in Windows Terminal, they stayed grayscale. Startup now waits for the first color query, which ends at the DA1 reply or after 100 ms.
* fix(coding-agent): rebuild header and notices on theme changes
The startup header, loaded resources, and chat notices baked theme colors into their text, so they kept the old colors after a theme switch or when the system theme received the terminal's colors. They now use ThemedText, which rebuilds its text from a function whenever the UI is invalidated.
* fix(tui): keep focus on components that forward mouse events to children
A component that forwards a mouse event to a child it hosts, such as SettingsList with an open submenu, left keyboard focus on the child. When the host removed the child, focus stayed on a detached component and all keys were lost. The forwarding component now keeps focus, like delegating containers do.
* feat(coding-agent): describe the system theme in the theme selector
* feat(coding-agent): list the system theme above automatic in the theme selector
* refactor(coding-agent,tui): remove leftovers of the light/dark startup detection
Theme detection only reports dark or light now; the source and confidence fields only served saving the detected theme. The first-time setup no longer shows the detected appearance. Removes the TUI's unused queryTerminalColorScheme(), queryTerminalBackgroundColor(), queryTerminalForegroundColor(), and parseOsc11BackgroundColor(); queryTerminalColors() covers them.
* feat(coding-agent): match the reviewed system and light/dark theme design
The system theme now follows the reviewed design: color families with OKHSL saturation curves, palette slots per family, contrast rules per token and panel, relaxation for mid-gray backgrounds, and the terminal foreground for body text. Each contrast level is a target-lightness curve fitted to the reviewed output. The built-in dark and light themes use the reviewed Pi dark and light colors.
* feat(coding-agent): show the pi logo in the startup header
A two-line pixel logo replaces the app name. Its first line carries the version, its second line the first line of key hints.
* feat(tui,coding-agent): support OKHSL colors in themes
parseColor() accepts okhsl(H S L), and okhslColor() and colorToOkhsl() construct and read OKHSL colors. OKHSL saturation is relative to the sRGB gamut, so every value is in gamut. Theme files accept okhsl() values; HTML exports convert them to hex. The OKHSL code moves from coding-agent into pi-tui, where colors.ts now shares its Oklab conversion instead of keeping a second copy.
* refactor(coding-agent): write the built-in themes in OKHSL
The built-in dark and light themes use okhsl() values, with variables for colors that several roles share, so they read as color families and serve as editable templates. Near-identical values collapsed into one; no color changes visibly.
* refactor(coding-agent,tui): simplify terminal color and theme code
Share the terminal color query between startup and the theme controller, merge the query's resolve/late-reply state into one callback, keep a single global for terminal colors, use oklab.ts arrays directly in colors.ts, and drop leftover helpers and exports.
* fix(coding-agent): use one terminal light/dark decision everywhere
Theme pairs, the system theme, and Theme.appearance now share getTerminalTheme(): the reported background decides, then the terminal's light/dark report, then COLORFGBG, then dark.
COLORFGBG is classified by palette index like Vim (0-6 and 8 dark) and only reads the last field, so rxvt's "default" no longer picks up the foreground index.
Simplify the tests added on this branch.
* fix(ai): use an OpenRouter model that still exists in beta test
OpenRouter removed anthropic/claude-3-haiku, which broke type checking in CI after model regeneration.
Closing the last overlay hid the terminal cursor. If an extension closed
an overlay during session shutdown, this ran after stop() had restored
the cursor, leaving the shell with an invisible cursor.

Replace the tsgo native preview with typescript@7.0.2 and port the check scripts to the TS 7 API. Target ES2024, drop useDefineForClassFields: false and unused decorator options, and enable verbatimModuleSyntax. Replace tsx with node plus the source resolver hook, passed to --import as a file URL.

Expose theme colors as values and add theme.style() for combined styling.
- @earendil-works/pi-tui gains a Color type (palette index, sRGB, OKLCH) with parseColor(), mixColors(), colorToHex(), colorToRgb(), styleText() and related helpers.
- Theme JSON accepts #rgb and oklch(...) values and an optional appearance ("dark" or "light"), detected from the theme colors when omitted.
- theme.style() combines tokens or concrete colors with text attributes; theme.colors exposes concrete colors, including the terminal's reported default colors (OSC 10/11) for tokens set to "".
- Terminals with TERM=*-direct are detected as truecolor.
Replace the external clipboard dependency with small macOS, Windows,
and X11 helpers and integrate them into coding-agent.
Run native clipboard operations on worker threads and make command
fallbacks asynchronous. Preserve incremental X11 transfers, legacy text
encodings, native image formats, and existing Wayland and platform tools.
Include native prebuilds with ARM64 page alignment, packaging updates,
and regression coverage.
