chore: bump version

SerieScanner attempted to assign serie.episodeDict = missing_episodes
but the property had no setter, causing AttributeError during scan.

Added setter that stores value in _episode_dict_cache, which the getter
already checks. This allows SerieScanner to update episodeDict directly.

+
+### Fixed
+
+- **Folder scan series key resolution**: Fixed "Could not resolve series key for folder, skipping" warnings during library setup. `_resolve_key_via_search()` now uses fuzzy title matching instead of exact string comparison.
+    - Added `_normalize_title()` to strip anime suffixes: `(TV)`, `(Anime)`, `(OAD)`, `(OVA)`, `(Special)`, `(Movie)`, `(Spin-Off)`
+    - Added `_titles_match()` using `difflib.SequenceMatcher` with 0.85 similarity threshold for tolerance of minor title variations
+    - Added debug logging for title mismatches and multiple search results

+# Navigation & Redirect Logic
+
+This document describes the setup flow navigation, covering how users progress from initial setup through to the main application.
+
+## Overview
+
+The application uses a middleware-based redirect system to enforce a strict state machine. Users must complete each phase before accessing the next. Attempting to bypass the current phase redirects to the appropriate page.
+
+## State Machine
+

+
+## State Definitions
+
+| State | Condition | Target Page |
+|-------|-----------|-------------|
+| `NO_SETUP` | No master password configured | `/setup` |
+| `SETUP_COMPLETE` | Initial config passed, loading not started | `/loading` |
+| `UNRESOLVED_PENDING` | Setup done, unresolved exist, not marked done | `/setup/unresolved` |
+| `UNRESOLVED_DONE` | Unresolved phase marked complete, NFO scan pending | `/loading` |
+| `NFO_SCAN_PENDING` | Unresolved done, NFO scan incomplete | `/loading` |
+| `COMPLETE` | All phases finished | `/login` |
+
+## Middleware: SetupRedirectMiddleware
+
+**File:** `src/server/middleware/setup_redirect.py`
+
+The middleware intercepts all requests and enforces the state machine.
+
+### Exempt Paths (always accessible)
+
+| Path | Purpose |
+|------|---------|
+| `/setup` | Initial setup page |
+| `/setup/unresolved` | Unresolved folder resolution |
+| `/loading` | Initialization progress page |
+| `/login` | Authentication |
+| `/api/auth/*` | Auth endpoints |
+| `/api/config/*` | Config API |
+| `/api/health` | Health check |
+| `/static/*` | Static assets |
+
+### Middleware Logic
+
+The middleware checks the current state and redirects accordingly:
+
+```
+1. NO_SETUP state:
+   → Redirect ALL requests to /setup
+   → Exception: /setup itself is accessible
+
+2. SETUP_COMPLETE state:
+   → Redirect /setup to /loading
+   → Redirect any other page to /loading
+
+3. UNRESOLVED_PENDING state (unresolved folders exist, not marked done):
+   → Redirect /setup to /setup/unresolved
+   → Redirect /loading to /setup/unresolved
+   → Allow access to /setup/unresolved
+   → Redirect any other page to /setup/unresolved
+
+4. UNRESOLVED_DONE state (unresolved marked done, NFO scan pending):
+   → Redirect /setup to /loading
+   → Redirect /setup/unresolved to /loading
+   → Redirect any other page to /loading
+
+5. NFO_SCAN_PENDING state:
+   → Redirect /setup to /loading
+   → Redirect /setup/unresolved to /loading
+   → Allow access to /loading (NFO phase runs)
+   → Redirect any other page to /loading
+
+6. COMPLETE state (loading finished):
+   → Redirect /setup, /loading, /setup/unresolved to /login
+   → Allow access to /login and main app
+```
+
+### Phase Tracking Flags
+
+| Flag | Purpose |
+|------|---------|
+| `setup_complete` | Initial configuration was saved |
+| `loading_started` | Loading phase has been initiated (redirected to /loading) |
+| `unresolved_completed` | User clicked "Done" on unresolved page |
+| `loading_complete` | Series scan + initial loading finished |
+| `nfo_scan_complete` | Final NFO scan finished |
+
+## Pages
+
+### 1. Setup Page (`/setup`)
+
+**File:** `src/server/web/templates/setup.html`
+
+Handles initial configuration:
+- Master password creation
+- Anime directory selection
+- Database initialization
+
+**Allowed in states:** `NO_SETUP`
+
+**Post-completion:**
+- Sets `setup_complete` flag
+- Redirects to `/loading`
+
+### 2. Loading Page (`/loading`)
+
+**File:** `src/server/web/templates/loading.html`
+
+Shows initialization progress via WebSocket:
+- Series scanning
+- Database population
+- Logo/image loading
+
+**Allowed in states:** `SETUP_COMPLETE`, `UNRESOLVED_DONE`, `NFO_SCAN_PENDING`
+
+**Post-initialization (series scan complete):**
+```javascript
+async function checkUnresolvedAndProceed() {
+    const res = await fetch('/api/setup/unresolved', {
+        headers: { 'Authorization': `Bearer ${token}` }
+    });
+    const folders = await res.json();
+    
+    if (folders.length > 0) {
+        window.location.href = '/setup/unresolved';
+    } else {
+        window.location.href = '/login';
+    }
+}
+```
+
+**Post-NFO scan:**
+- Sets `nfo_scan_complete` flag
+- Redirects to `/login`
+
+### 3. Unresolved Folders Page (`/setup/unresolved`)
+
+**File:** `src/server/web/templates/unresolved.html`
+
+Allows manual resolution of folders that couldn't be auto-matched:
+- Shows list of unresolved folders
+- Provides search suggestions
+- Input field for entering provider key
+- Resolve/delete actions
+- **Done button** to complete the phase without resolving all folders
+
+**Allowed in states:** `UNRESOLVED_PENDING`
+
+**Done button behavior:**
+- Sets `unresolved_completed` flag
+- Redirects to `/loading` for final NFO scan
+
+**After completion:**
+- Any access redirects to `/loading`
+
+### 4. Login Page (`/login`)
+
+**File:** `src/server/web/templates/login.html`
+
+Authentication page. After successful login → redirect to `/` (main app).
+
+**Allowed in states:** `COMPLETE`
+

-# Migration Guide: File-Based to Database Storage
-
-## Overview
-
-This guide covers the transition from file-based series metadata storage to the new database-backed system introduced in v2.0.
-
-## What Changed
-
-**Before v2.0**: Series metadata stored in `key` and `data` files alongside anime folders.
-
-**After v2.0**: All metadata stored in SQLite database (`aniworld.db`). Files are deprecated but still supported for backward compatibility during migration.
-
-## Automated Migration
-
-The application automatically migrates on first startup:
-
-1. Scans anime directory for `key` and `data` files
-2. Parses legacy files into `AnimeSeries` and `Episode` records
-3. Loads series into in-memory cache
-4. Logs migration results
-
-**No manual action required.**
-
-## Manual Verification
-
-After first startup with the new version:
-
-1. **Check logs** for: `"Migrated X series from files to DB"`
-2. **Verify series count**: UI shows same number of series as before
-3. **Confirm episodes**: Episode counts match expected totals
-
-```bash
-# Check migration log
-grep "Migrated" logs/app.log
-
-# Verify series via API
-curl http://localhost:8000/api/anime | jq '.total'
-```
-
-## After Migration
-
-### Safe to Delete
-
-Once verified, these files can be removed:
-
-```
-<anime_folder>/
-├── Attack on Titan (2013)/
-│   ├── key     # ❌ Can delete
-│   ├── data    # ❌ Can delete
-│   └── Season 1/
-│       └── ...
-```
-
-**Deleting these files does not affect the database.** The metadata now lives in `aniworld.db`.
-
-### Backup (Recommended)
-
-Before deleting, backup the files:
-
-```bash
-# Create backup directory
-mkdir -p backup/legacy_series_files
-
-# Copy all key and data files
-find /path/to/anime -name "key" -o -name "data" | while read f; do
-    cp "$f" "backup/legacy_series_files/"
-done
-```
-
-## Reverting (Not Recommended)
-
-If you must revert to file-based storage:
-
-1. **Restore from database backup** (if available)
-2. **Export manually** (no export script exists)
-
-**Warning**: File-based storage is deprecated and will be removed in v3.0.0.
-
-## Troubleshooting
-
-### Series Not Appearing After Migration
-
-1. Check logs for migration errors: `grep -i error logs/app.log`
-2. Verify `key` and `data` files exist and are readable
-3. Manually trigger rescan: `POST /api/scheduler/trigger-rescan`
-
-### Duplicate Series
-
-1. Check for duplicate `key` files (same series in multiple folders)
-2. Verify series key uniqueness in database:
-
-```bash
-sqlite3 aniworld.db "SELECT key, COUNT(*) FROM anime_series GROUP BY key HAVING COUNT(*) > 1;"
-```
-
-### Missing Episodes
-
-1. Trigger targeted scan for affected series
-2. Check episode sync logs
-3. Verify file permissions on anime directory
-
-## Deprecation Timeline
-
-| Version | Status |
-|---------|--------|
-| v2.0.x  | Legacy files supported, migration automated |
-| v2.1.x  | Legacy files still supported, warnings in logs |
-| v3.0.0  | **Legacy files removed** - database only |
-
-Upgrade to v3.0.0 before legacy file support ends.
