mountain 9ad54122bb fix: resolve concurrency and DoS pitfalls from PR #272 review
- index/utils.py: fix an asyncio deadlock in _sync_llm_semaphore. Sync LLM
  calls (check_toc / process_no_toc / toc_transformer) run on the event-loop
  thread nested inside the async meta_processor, and its blocking ceiling
  acquire could wait forever for a permit held by async _llm_semaphore holders
  that can only release it once the (now-frozen) loop runs. Take the slot
  non-blocking when on a running loop; keep the blocking acquire off-loop.
- index/utils.py: bound parse_pages ranges before materializing range() into
  the list, so a huge span like '1-2000000000' is rejected up front instead of
  exhausting memory before the 1000-page cap is ever checked (DoS).
- storage/sqlite.py: bump a generation counter on close() so a thread that
  cached a connection in thread-local storage reconnects on its next call
  instead of reusing a closed handle (ProgrammingError).
- backend/cloud.py: after connect, bail out of the SSE background thread if the
  consumer already abandoned the stream, instead of draining it in the background.

Adds regression tests for each fix.
