**Summary:**
- Add tint overlay to dim terminal windows when inactive, fixes
https://github.com/ghostty-org/ghostty/discussions/10040
- Refactor the liquid glass effect into a dedicated `TerminalGlassView`
class
Note: The tint overlay color and opacity values may not be ideal —
feedback is welcome.
**AI Disclosure:** I used Claude Code to read the macos repo and
understand the liquid glass implementation. Implemented basic tint
overlay mainly by hand. Refactor the code and review changes with Claude
Code.

#9617.
Rendering the Secure Keyboard Input overlay using innerShadow() can
strain the resources of the main thread, leading to elevated CPU load
and in some cases extended disruptions to the main thread's
DispatchQueue that result in lag or frozen frames. This change achieves
the same animated visual effect with ~35% lower CPU usage and resolves
most or all of the terminal rendering issues associated with the
overlay.

We already had an established Ghostty.Shell namespace (previously a
struct; now a more idiomatic enum), and locating these functions next to
each other makes it clearer how they relate to one another.
When we're building an input string that's explicitly meant to be used
as a shell command, quote (escape) it using the same logic as Python's
shlex.quote function.
This specifically addresses issues we've seen when open(1)'ing Ghostty
with filename arguments that contain spaces.
Clicking on the icon immediately advances to the next one. Hovering on
the icon pauses the automatic cycling, and the "help" tooltip displays
the icon's configuration name (for `macos-icon`).
