The old Linux-only guard only rejected absurd sizes (>8K) as corruption
sentinels; anything under that was passed through to the builder
verbatim. So a size saved on a 4K display would open on a 1080p display
at full 4K dimensions — off-screen, unreachable when decorations are
hidden.
Added a second clamp inside setup() that queries app.available_monitors()
after Tauri has the display connection, takes the largest logical size
across all connected monitors, and shrinks the persisted size to 95% of
that when it overflows. The original 8K corruption guard stays as a
first pass (runs before setup, catches corrupt DB rows before we even
open a display connection).
Works on all platforms — no cfg gating, since 'saved size bigger than
any monitor' is a user-visible problem everywhere, and the 8K guard
also protects macOS/Windows against a corrupt settings row.
