cliffhall	59cc89dbe9	Fix the inspector caching problem * I've noticed that on a new version of the inspector, I have to go to the browser's devtools panel and clear site data then reload the page. * The assets are hashed and immutable, so caching should be allowed for them * The index.html file is the problem, because if cached, it will point to old assets, and therefore needs to have caching turned forf * This PR adds appropriate headers to the index.html and assets that are served.	2025-04-30 17:31:58 -04:00
cliffhall	79a09f8316	Consolidate hooks * Hooks are in multiple places in the codebase and some camelCase, some snake-case. This PR relocates them all to the lib/hooks folder and normalizes camelCase naming. Settled on src/client/lib/hooks for the location since most of them were already there. - Refactor/move useTheme.ts from client/src/lib to client/src/lib/hooks - Refactor/move useToast.ts from client/src/hooks/ to client/src/lib/hooks/useToast.ts - Removed client/src/hooks	2025-04-30 17:09:22 -04:00
