Subject: [PATCH] fix(bridge): resolve data dir same as Python for
 sync-result.json

Both readSyncResult() and probeAll() now mirror Python's
_resolve_data_dir() logic: dev detection (cwd/.obsidian-rag
or cwd/KnowledgeVault) then home dir fallback.

Previously readSyncResult always used cwd/.obsidian-rag (wrong for
server deployments) and probeAll resolved sync-result.json relative
to db path (wrong for absolute paths like /home/san/.obsidian-rag/).
