list_wings/get_taxonomy truncated at 10,000 drawers (hardcoded limit)

[devtony42]

Bug

tool_list_wings(), tool_list_rooms(), and tool_get_taxonomy() in mcp_server.py use col.get(include=["metadatas"], limit=10000). When the palace exceeds 10,000 drawers, wings/rooms beyond the first 10K are invisible in listings.

Search works correctly since col.query() searches the full index.

Reproduction

1. Mine enough content to exceed 10,000 drawers
2. Call mempalace_list_wings — only wings from the first 10K drawers appear
3. Call mempalace_search with a wing filter for a missing wing — results found correctly

Environment

• MemPalace 3.1.0
• ChromaDB 0.6.3
• 27,714 drawers across 47 wings

Suggested Fix

Replace the hardcoded limit=10000 with col.count():

total = col.count()
all_meta = col.get(include=["metadatas"], limit=max(total, 10000))["metadatas"]

This ensures all drawers are scanned for listing operations regardless of palace size.

Affects: mcp_server.py lines ~205, ~220, ~238 (three occurrences).

MCP tools (list_wings, list_rooms, get_taxonomy) now use _fetch_all_metadata() which paginates in batches of 1000 instead of the old hardcoded limit=10000. Landed via #707. See also #171, #688.
