feat: Add caching layer and batch operations for improved performance

Browse Source 
Implement Phase 3 improvements: intelligent caching and batch operations
to significantly enhance SDK performance and usability.

**1. Caching Layer Implementation**

Added complete caching infrastructure with LRU eviction and TTL support:

- `wikijs/cache/base.py`: Abstract BaseCache interface with CacheKey structure
- `wikijs/cache/memory.py`: MemoryCache implementation with:
  * LRU (Least Recently Used) eviction policy
  * Configurable TTL (time-to-live) expiration
  * Cache statistics (hits, misses, hit rate)
  * Resource-specific invalidation
  * Automatic cleanup of expired entries

**Cache Integration:**
- Modified `WikiJSClient` to accept optional `cache` parameter
- Integrated caching into `PagesEndpoint.get()`:
  * Check cache before API request
  * Store successful responses in cache
  * Invalidate cache on write operations (update, delete)

**2. Batch Operations**

Added efficient batch methods to Pages API:

- `create_many(pages_data)`: Batch create multiple pages
- `update_many(updates)`: Batch update pages with partial success handling
- `delete_many(page_ids)`: Batch delete with detailed error reporting

All batch methods include:
- Partial success support (continue on errors)
- Detailed error tracking with indices
- Comprehensive error messages

**3. Comprehensive Testing**

Added 27 new tests (all passing):

- `tests/test_cache.py`: 17 tests for caching (99% coverage)
  * CacheKey string generation
  * TTL expiration
  * LRU eviction policy
  * Cache invalidation (specific & all resources)
  * Statistics tracking

- `tests/endpoints/test_pages_batch.py`: 10 tests for batch operations
  * Successful batch creates/updates/deletes
  * Partial failure handling
  * Empty list edge cases
  * Validation error handling

**Performance Benefits:**
- Caching reduces API calls for frequently accessed pages
- Batch operations reduce network overhead for bulk actions
- Configurable cache size and TTL for optimization

**Example Usage:**

```python
from wikijs import WikiJSClient
from wikijs.cache import MemoryCache

# Enable caching
cache = MemoryCache(ttl=300, max_size=1000)
client = WikiJSClient('https://wiki.example.com', auth='key', cache=cache)

# Cached GET requests
page = client.pages.get(123)  # Fetches from API
page = client.pages.get(123)  # Returns from cache

# Batch operations
pages = client.pages.create_many([
    PageCreate(title="Page 1", path="page-1", content="Content 1"),
    PageCreate(title="Page 2", path="page-2", content="Content 2"),
])

updates = client.pages.update_many([
    {"id": 1, "content": "Updated content"},
    {"id": 2, "is_published": False},
])

result = client.pages.delete_many([1, 2, 3])
print(f"Deleted {result['successful']} pages")
```
