Replace the single coarse mutex protecting all text index writes with a two-level scheme: a sharded per-word bucket mutex pool for Postings updates and an absl reader-writer lock for tree structural changes. This allows concurrent writes to independent words to proceed in parallel rather than serializing all writer threads. Search reads now hold a shared reader lock and no longer block concurrent writes to existing words. The tree write lock is only acquired when a word is first inserted or fully removed.
