  3. reduce CGO call overhead for exec and bind paths 

    - Add _sqlite3_exec_no_args() C function that combines prepare+step+finalize
  into a single CGO crossing for parameterless exec (most common case)
- Add _sqlite3_reset_clear() C function that combines sqlite3_reset and
  sqlite3_clear_bindings into a single CGO crossing
- Use semaphore channel instead of result struct channel in context-aware
  exec/Next paths to reduce allocations
- Use time.AppendFormat with stack buffer to avoid heap allocation in
  time.Time binding
- Optimize bindNamedIndices to reuse a single buffer instead of 3
  separate C.CString allocations
- Remove intermediate bindIndices slice allocation in named parameter
  binding path
- Pass explicit query length to sqlite3_prepare_v2 to avoid C-side strlen

  4. fix build with SQLITE_ENABLE_UNLOCK_NOTIFY 

    Move extern declarations for _sqlite3_*_blocking functions before
_sqlite3_exec_no_args which references them. Remove unused
_sqlite3_prepare_v2_nolen function.
