fix(libmdbx): merge loose pages from parallel subtxns to parent Parallel subtxns in WRITEMAP mode can accumulate loose pages when deleting entries. These pages were previously leaked until parent commit. Fix: - On subtxn commit: merge loose_pages to parent's repnl for reuse - On subtxn abort: clean up loose_pages in subtx_free_resources

docs(libmdbx): document all parallel subtxn invariants Add comprehensive documentation for parallel subtxn contract: - NO READ-THROUGH: subtxns see parent's state at creation time only - NO CROSS-DBI: enforced by cursor_bind - SERIAL COMMIT: subtxns must commit before parent - DISJOINT PAGES: each DBI has separate B-tree Add THREAD SAFETY section explaining: - Concurrent execution on different threads - Mutex-protected page allocation - Per-subtxn page_auxbuf for DupSort isolation

docs(libmdbx): document parallel subtxn changes and invariants Add documentation comments explaining: - Per-txn page_auxbuf for thread-safe DupSort operations - 1 DBI = 1 SUBTXN invariant for isolation - geo.first_unallocated synchronization across siblings - Parallel subtxn creation/commit semantics - DEBUG timing logs are zero-cost in release builds

fix(libmdbx): allocate page_auxbuf for parallel subtxns Parallel subtxns were setting tw.txn_page_auxbuf but cursor_put checks tw.page_auxbuf, causing all parallel subtxns to fall back to shared env->page_auxbuf - a data race for DupSort operations. Now each parallel subtxn allocates its own tw.page_auxbuf scratch buffer, matching the behavior of regular nested txns.
