too many quirks in window dimensions

[mcandre]

Issue Description

ghostty breaks (mac)OS conventions for GUI window dimensions.

Expected Behavior

• ghostty should generally respect window-height, window-width. For fresh launches. For new windows. For relaunches. Only alter the dimensions in the event that the user resizes/tiles the window.
• When either of these two attributes are not explicitly customized, then automatically fallback on values from the last window's dimensions. window-save-state = always should trigger some kind of disk persistence, every single time live window location and/or dimensions change.
• Don't forcibly preserve cwd with window-save-state = always.

Actual Behavior

• Fresh launches of ghostty completely ignore window-height and window-width on macOS.
• Closing the last window prior to relaunching ghostty, produces a window half my normal width.
• New windows ignore window-height, window-width, and window-save-state = always.
• window-save-state = always forces the current working directory to persist across relaunches. While some users may prefer that behavior, we should provide a separate setting so that cwd preservation with window-save-state = always can operate independently.
• Similar quirks when quit-after-last-window-closed = true is in effect. I was hoping that one would act as a workaround to how ghostty forgets persisted dimensions on save when the last window is closed prior to quitting... but it actually makes the problem even worse.

These quirks are not fun, and it's too bad, because every single macOS terminal emulator has just as many nasty quirks like that.

Would be helpful to add options like window-location: top-right, window-height: full, window-width: 50%, to assist with tiling centric workflows.

Reproduction Steps

Repeatedly launch, place ghostty windows, create new windows, and relaunch.

Use ordinary cursor window resizing and moving.

Use native macOS tiling.

Use Rectangle tiling.
