Claude 423d209d16 LR-PREF-DISPLAY: Windows previews follow the monitor's colour profile ...

While no monitor profile is chosen in Settings > Display, Windows now shows
previews through the profile Windows Color System assigns to the monitor
showing the window (per-user or system), as macOS and Linux already do. It is
read about once a second, so moving the window to another monitor and changing
the profile in Windows are followed without a restart. While Windows
colour-manages the desktop itself (HDR, Auto Color Management), previews stay
sRGB.

The Win32 calls live in a new L0 helper crate, crates/wincolor, the second
crate allowed `unsafe` after crates/sysmem (SAFETY comments on every block,
safe API, Unknown on any failure); CLAUDE.md and AGENTS.md name it. GDI's
GetICMProfileW keeps the profile a process first saw, so WCS is read directly
and GetICMProfileW is only a fallback.

The profile-file loader moves from the Linux-only colord.rs to a shared
profile_file.rs (unchanged), with a cache that re-reads a file only when it
changes.

Verified on Windows 11 by setting and clearing a Display P3 profile and
toggling HDR while the app ran.
