feat: entity cache system, nav UX improvements, split CLAUDE.md

- Add $state-based entity cache layer with 30s TTL, request deduplication,
  and local mutation helpers (entity-cache.svelte.ts + caches.svelte.ts)
- Wire all 10 page components to use shared caches for cross-page data
- Add slide animation for nav tree expand/collapse with rotating chevron
- Remove aggregate count badges from container nav nodes (keep on leaves)
- Convert Targets from flat leaf to group with per-type children
  (Telegram, Webhook, Email, Discord, Slack, ntfy, Matrix)
- Add URL-based type filtering on Targets page with per-type descriptions
- Add Bots group children for Email and Matrix alongside Telegram
- Tab-based routing for bots page (?tab=telegram/email/matrix)
- Add per-type target counts and email/matrix bot counts to /status/counts
- Split CLAUDE.md into focused context files under .claude/docs/
- Fix .gitignore: scope lib/ to root, allow .claude/docs/ tracking
- Clear all caches on logout
- Reset form state when switching target type tabs

+# Frontend Architecture Notes
+
+## Stack
+
+- **SvelteKit 2 + Svelte 5 + Tailwind CSS v4** — Static adapter with SPA fallback. Dev proxy to :8420.
+- **Tailwind CSS v4**: Uses `@theme` directive in `app.css` for CSS variables.
+
+## Svelte 5 Runes
+
+- `$state` only works in `.svelte` and `.svelte.ts` files. Regular `.ts` files cannot use runes — use plain variables instead.
+
+## i18n
+
+- Uses `$state` rune in `.svelte.ts` file. Locale auto-detects from localStorage.
+- `t()` is reactive via `$state`. `setLocale()` updates immediately without page reload.
+
+## Auth Flow
+
+- After login/setup, use `window.location.href = '/'` (hard redirect), NOT `goto('/')`.
+
+## Overlays
+
+**IMPORTANT**: Overlays (modals, dropdowns, pickers) MUST use `position: fixed` with inline styles and `z-index: 9999`. Tailwind CSS v4 `fixed`/`absolute` classes do NOT work reliably inside flex/overflow containers in this project. Always calculate position from `getBoundingClientRect()` for dropdowns, or use `top:0;left:0;right:0;bottom:0` for full-screen backdrops.
+
+## Entity Cache System
+
+Shared entities use a `$state`-based cache layer in `frontend/src/lib/stores/`:
+
+- **`entity-cache.svelte.ts`** — Generic cache factory with 30s TTL, request deduplication, and local mutation helpers (`upsert`, `remove`, `set`).
+- **`caches.svelte.ts`** — Singleton caches for: `providersCache`, `targetsCache`, `trackingConfigsCache`, `templateConfigsCache`, `telegramBotsCache`, `emailBotsCache`, `matrixBotsCache`, `commandConfigsCache`, `commandTemplateConfigsCache`.
+
+### How pages use caches
+
+- **Cross-page references** (e.g. providers on the Trackers page): Use `$derived(providersCache.items)` and call `providersCache.fetch()` in `load()`. Cached data is returned instantly if fresh (<30s).
+- **Owning pages** (e.g. Providers page itself): Use `$derived(providersCache.items)` and call `providersCache.fetch(true)` (force refresh) in `load()`.
+- **After mutations** (create/update/delete): The owning page calls `cache.invalidate()` then `load()` to force-refresh. Other pages pick up changes on next navigation via TTL expiry.
+- **On logout**: `clearAllCaches()` is called to wipe all cached data.
+
+### Adding a new cached entity
+
+1. Add a type to `frontend/src/lib/types.ts`
+2. Add `export const fooCache = createEntityCache<Foo>('/foo');` to `caches.svelte.ts`
+3. Add `fooCache.clear()` to `clearAllCaches()`
+4. In page components: replace `let foo = $state<Foo[]>([])` with `let foo = $derived(fooCache.items)` and replace `api('/foo')` with `fooCache.fetch()`

+# Template System Sync Rules
+
+**IMPORTANT**: When adding or changing template context variables, you MUST update ALL of these in sync:
+1. **`packages/core/.../templates/context.py`** — `build_template_context()` where variables are computed
+2. **`packages/server/.../api/template_configs.py`** — `_SAMPLE_CONTEXT` dict (for preview rendering)
+3. **`packages/server/.../api/template_configs.py`** — `get_template_variables()` endpoint (`event_vars`, `asset_fields`, `album_fields`, `scheduled_vars`, per-slot variable dicts)
+4. **`packages/core/.../templates/defaults/{en,ru}/*.jinja2`** — default template files using the new variables
+5. **`packages/core/.../providers/immich/provider.py`** — `IMMICH_VARIABLES` list (provider-specific variable definitions)
+6. **`packages/server/.../api/command_template_configs.py`** — `get_command_variables()` endpoint (for command response templates)
+
+**IMPORTANT**: Variable reference endpoints MUST document child/nested properties, not only top-level variables. When a variable is a list of dicts (e.g. `assets`, `albums`, `events`, `commands`), the endpoint MUST include a corresponding `*_fields` dict describing the child properties (e.g. `asset_fields: {"id": "...", "filename": "..."}`) so the frontend can show them (e.g. `{{ asset.id }}`, `{{ album.name }}`). Never list only `"assets": "List of asset dicts"` — always specify what fields each dict contains.

+3. **Template variables** must be updated in 6 files simultaneously — see [template-system.md](.claude/docs/template-system.md).

+4. **Entity cache** — shared entities use `$state`-based caches in `frontend/src/lib/stores/caches.svelte.ts`. Always use cache for cross-page data; invalidate after mutations — see [frontend-architecture.md](.claude/docs/frontend-architecture.md).
