Upstream v3.3.1 headline: multi-language entity detection (PT-BR, Russian,
Italian, Hindi, Indonesian, Chinese), BCP-47 case-insensitive locale
resolution, UTF-8 encoding fix for non-UTF-8 Windows locales, combining-mark
word-boundary fix for Devanagari/Arabic/Hebrew/Thai scripts. Also absorbs
PR MemPalace#966 (honor silent_save), MemPalace#863 (precompact blocking fix), MemPalace#895/MemPalace#897
(benchmarks + README rewrite), MemPalace#946 (UTF-8 Path.read_text), and more.

Conflict resolutions:

- mempalace/hooks_cli.py: kept fork-only _desktop_toast + _mempalace_python
  (hook wrappers depend on these), adopted upstream's _get_mine_dir helper +
  _mine_sync function + _maybe_auto_ingest(transcript_path) signature, kept
  fork's silent-save MempalaceConfig branch, kept _ingest_transcript call
  in hook_precompact before the new _mine_sync so the session JSONL still
  gets captured on precompact.
- tests/test_hooks_cli.py: merged both import sets. Updated
  test_stop_hook_rejects_injected_stop_hook_active to accept either the
  silent-save systemMessage output or the legacy decision=block — the
  security property (don't treat injected stop_hook_active as truthy) holds
  for both modes.
- tests/test_miner.py: merged both import sets (CHUNK_* constants +
  load_config).
- tests/test_readme_claims.py: accepted upstream's shift from README
  parsing to website/reference/mcp-tools.md and modules.md — website docs
  are now the source of truth for the tool table.
- mempalace/entity_detector.py: accepted upstream wholesale — replaces
  hardcoded English STOPWORDS with i18n-JSON-backed patterns and backward-
  compat module constants.
- README.md: kept fork README, bumped version badge 3.3.0 → 3.3.1.

Verification: 995 tests pass, stop hook fires end-to-end ("✦ 13 memories
woven into the palace"), 10/10 fresh-process palace opens + queries OK.

- Bump fork-target tag and drawer count (v3.3.0 → v3.3.1, 134K → 135K)
- Add "Pulled in from upstream v3.3.1" section: i18n entity detection,
  BCP-47 locale resolution, script-aware boundaries, UTF-8 Path.read_text,
  non-blocking precompact (MemPalace#863), basic silent_save honoring (MemPalace#966)
- Note that our MemPalace#673 silent-save is still ahead of upstream's MemPalace#966:
  marker-after-confirmed-save, themes extraction, systemMessage
- Add Mintlify to the memory-system comparison table (docs platform
  pitched as "self-updating knowledge management" with MCP support;
  not a verbatim personal memory tool, but shares the framing)

README:
- Bump drawer count 134K → 137K (matches current palace)
- Update "Open upstream PRs" table with actual reviewer status, add MemPalace#999
  and MemPalace#1000, drop stale "rebased against MemPalace#863" note since MemPalace#863 is in v3.3.1

CLAUDE.md:
- Rename section header v3.3.0 → v3.3.1 (we merged v3.3.1 earlier today)
- Add fork changes 11-13: None-metadata guards, .blob_seq_ids_migrated
  marker, quarantine_stale_hnsw
- Replace "Pulled in from upstream v3.3.1" summary: i18n, BCP-47 locales,
  UTF-8 Path.read_text, non-blocking precompact (MemPalace#863), silent_save
  honoring (MemPalace#966) — ours still broader
- Update the open-upstream-PRs table to 7 open, include MemPalace#999 + MemPalace#1000 and
  refresh each row's status line to match what's actually on GitHub
  (MERGEABLE flags, @bensig ping context, Copilot review addressed, etc.)
