Slim list_vault to bare index, add get_file_info for detail
list_vault: Each entry now ~55 chars (name+path+type) vs ~120 before. - Dropped size_bytes (was 0 for dirs, wasted tokens) - Dropped modified date (moved to get_file_info) - .obsidian hidden by default (include_hidden=True to opt in) - Uses _file_info_lean helper New get_file_info tool: Full metadata for a single file. - size_bytes, modified (YYYY-MM-DD), line_count, char_count All dates compacted: '2025-06-10' vs '2025-06-10T23:40:11.798359+00:00' (22 chars saved per date, ~10x token savings) Added shared helpers: - _compact_date() for YYYY-MM-DD everywhere - _is_hidden_path() replacing 4 duplicate filter blocks Estimated payload reduction for 311-note vault: ~55% on files, plus elimination of entire .obsidian config subtree.
