perf: skip page cache allocation for in-memory databases #274
Description
Problem
OpenOptions::page_cache_size is respected even when opening an in-memory database via open_memory(). The PageCache struct is allocated at full capacity (default 256 pages = 1MB), but all reads hit RAM directly — the cache is never useful and wastes heap.
Proposed fix
In Minigraf::in_memory_with_options, ignore page_cache_size and allocate a zero-capacity
9B8E
PageCache (or skip allocation entirely). The MemoryBackend does not go through the page cache path, so this is a safe no-op change with no semantic impact.
Acceptance criteria
- In-memory databases do not allocate the page cache regardless of
page_cache_size. OpenOptions::page_cache_sizeis documented as file-backed only.- Existing in-memory tests pass unchanged.
