feat: render OSC 11 dynamic background per-pane under window translucency

A program can tint a pane's background with OSC 11 (`printf '\033]11;#rrggbb\a'`), for example an rc that tints the scratch pane to distinguish it. Under agterm's window translucency this was invisible: libghostty applies the color to its render state and fires `COLOR_CHANGE` only as a notification, but each surface renders `background-opacity 0` (the AppKit window backing supplies the tint), so the OSC color never showed.

`GhosttyCallbacks` now handles `COLOR_CHANGE` for the background kind and gives that surface its own `.color` config overlay, the same per-surface path as `session background color`, with `background-opacity = windowOpacity`. The pane renders its OSC tint translucently and per-pane, without touching the window backing or any other surface. It survives a config reload, an opacity change, and a dashboard open/close, and is deduped per prompt. The color is tracked on `GhosttySurfaceView.oscBackgroundColorHex` and released whenever a watermark or plain config replaces the overlay, so a re-emitted OSC right after `session background clear/set` still renders.

**Known limitation.** `session background color` cannot override a live OSC 11. libghostty stores OSC 11 in the terminal's dynamic `override` layer, config only sets `default`, and the renderer draws `override orelse default`. The pinned libghostty (commit `4dcb09ada`) exposes no API to reset the override, so while a program holds an OSC background an explicit `session background color` is masked until the program emits OSC 111 or the surface is recreated. This is documented in the libghostty rule. OSC 10/12 (foreground/cursor) render regardless of translucency and are not wired.

*Also splits the surface-I/O methods into `GhosttySurfaceView+IO.swift` to keep the file under the line cap.*
