feat: add TanStack Query v6 integration with SSR support (#441)
## Summary

This PR establishes the foundation for migrating from custom Svelte 5
resource classes to TanStack Query v6 for server state management. It
adds:

**Query Options Factories** (in `src/lib/api/queries/`):
- `party.queries.ts` - Party fetching with infinite scroll support
- `job.queries.ts` - Job and skill queries with pagination
- `user.queries.ts` - User profile, parties, and favorites queries

**Mutation Configurations** (in `src/lib/api/mutations/`):
- `party.mutations.ts` - Party CRUD with cache invalidation
- `grid.mutations.ts` - Weapon/character/summon mutations with
optimistic updates
- `job.mutations.ts` - Job and skill update mutations

**Deprecation Notices**:
- Added `@deprecated` JSDoc to `search.resource.svelte.ts` and
`party.resource.svelte.ts` with migration examples

**SSR Integration** (Phase 4):
- Created `+layout.ts` to initialize QueryClient for SSR support
- Updated `+layout.svelte` to receive QueryClient from load function
- Added SSR utilities in `src/lib/query/ssr.ts`:
  - `withInitialData()` - for pages using +page.server.ts
- `prefetchQuery()` / `prefetchInfiniteQuery()` - for pages using
+page.ts
  - `setQueryData()` - for direct cache population
- Added documentation in `src/lib/query/README.md`

**Component Wiring Examples** (Phase 5):
- `JobSelectionSidebar.svelte` - Migrated from `createJobResource()` to
`createQuery(() => jobQueries.list())`. Demonstrates client-side query
pattern with automatic loading/error states.
- `teams/[id]/+page.svelte` - Added `withInitialData()` pattern for SSR
integration. Server-fetched party data is used as initial cache value
with background refetching support.

**Migration Guide**:
- Added `src/lib/query/MIGRATION.md` with follow-up prompts for
remaining component migrations (JobSkillSelectionSidebar, search modal,
user profile, teams explore, Party mutations, resource class removal)

## Updates Since Last Revision

Fixed TypeScript type errors in the TanStack Query integration:
- `party.queries.ts`: Made `total` and `perPage` optional in
`PartyPageResult` interface to match adapter return type
- `ssr.ts`: Fixed `withInitialData` to properly handle null values using
`NonNullable<TData>` return type
- `job.mutations.ts`: Fixed slot indexing by casting through `unknown`
to `keyof typeof updatedSkills`

Type checks now pass for all files modified in this PR (16 remaining
errors are pre-existing project issues unrelated to this PR - paraglide
modules not generated, hooks.ts implicit anys).

## Review & Testing Checklist for Human

- [ ] **Verify app loads correctly**: The `+layout.ts` and
`+layout.svelte` changes are critical path - confirm the app still
renders
- [ ] **Test JobSelectionSidebar**: Open job selection sidebar and
verify jobs load correctly, search/filter works, and retry button works
on error
- [ ] **Test teams/[id] page**: Navigate to a party detail page and
verify it renders without loading flash (SSR data should be immediate)
- [ ] **Review type casts**: Check `job.mutations.ts:135` - the `as
unknown as keyof typeof` cast for slot indexing is a workaround for
jobSkills having string literal keys ('0', '1', '2', '3') while slot is
a number
- [ ] **Verify withInitialData behavior**: The `NonNullable<TData>`
return type change in `ssr.ts` should work correctly with `data.party`
which can be `Party | null`

**Recommended test plan**: 
1. Run `pnpm install` to ensure dependencies are up to date
2. Start dev server and verify the app loads without errors
3. Navigate to a party detail page (`/teams/[shortcode]`) - should
render immediately without loading state
4. Open job selection sidebar (click job icon on a party you can edit) -
verify jobs load and filtering works
5. Test error handling by temporarily breaking network - verify retry
button appears

### Notes


- Pre-existing project issues remain (paraglide modules not generated,
hooks.ts implicit anys) - these are unrelated to this PR
- Local testing could not run due to missing node_modules (vite not
found) - project setup issue
- TanStack Query devtools installation was skipped due to Storybook
version conflicts
- The existing `search.queries.ts` file was used as the pattern
reference for new query factories
- SSR approach uses hybrid pattern: existing `+page.server.ts` files
work with `withInitialData()`, while new pages can use `prefetchQuery()`
in `+page.ts`
- Migration guide includes 6 follow-up prompts for completing the
remaining component migrations

sv

Everything you need to build a Svelte project, powered by sv.

Creating a project

If you're seeing this, you've probably already done this step. Congrats!

# create a new project in the current directory
npx sv create

# create a new project in my-app
npx sv create my-app

Developing

Once you've created a project and installed dependencies with npm install (or pnpm install or yarn), start a development server:

npm run dev

# or start the server and open the app in a new browser tab
npm run dev -- --open

Building

To create a production version of your app:

npm run build

You can preview the production build with npm run preview.

To deploy your app, you may need to install an adapter for your target environment.
