popertots c7d7169cd2 Disable svelte/prefer-svelte-reactivity (SvelteDate purge rationale)
The rule pushes SvelteDate (svelte/reactivity), which this codebase
deliberately removed in 55b2c8c because it caused real bugs. All Date usage is
local wall-clock computation via parseWallClockDate helpers, not reactive
$state Date mutations, and the rule has no options to allowlist Date — so
disable it outright in the svelte block with a rationale comment. Restores a
clean eslint gate for the pre-commit hook and CI.
