docs(changelog): document init entity-detection overhaul in 3.3.3

Adds entries to the 3.3.3 section for the work that landed via #1148,
#1150, #1157, and #1175 (rescued from stacked feature branches into
develop via #1175). Without these entries the 3.3.3 release notes on
main would advertise only the hook/diary/search fixes that made it to
develop through the first direct merge.

Covers:
- Manifest + git-author entity detection (#1148)
- Regex detector accuracy improvements (#1148)
- Optional --llm classification with Ollama / openai-compat / Anthropic
  provider abstraction and interactive UX (#1150)
- Claude Code conversation scanner (#1150)
- Init → miner registry wire-up so confirmed entities actually reach
  drawer metadata tagging (#1157)
- Case-insensitive project dedup across all sources (#1175)
- `mempalace mine` skips the generated entities.json artifact

 - Treat empty string as "no filter" in `mempalace_search` `wing`/`room`; LLM agents that default to filling every optional parameter with `""` no longer get bounced with `must be a non-empty string`. (#1097, #1084)
 - Broaden `_wing_from_transcript_path` to handle Claude Code project folders without a `-Projects-` segment (e.g. `~/dev/<parent>/<project>`, `~/code/<project>`). The project name is now derived from the final dash-separated token of the encoded folder, so Linux users with code outside `~/Projects/` get per-project diary scoping instead of falling through to `wing_sessions`. (#1145, follow-up to #659)
 - `mempalace_diary_read(wing="")` now returns diary entries from every wing this agent has written to, matching the #1097 "empty-string as no filter" pattern. Previously defaulted to `wing_<agent>`, siloing entries that hooks wrote to project-derived wings. (#1145)
+- `mempalace mine` now skips the generated `entities.json` file so its contents aren't re-ingested as project content.
 
 ### Improvements
 
 - **Deterministic hook saves.** Save hook now uses a silent Python API path, so successive hook invocations produce reproducible results and zero data loss on the hot path. (#673)
 - **Graph cache with write-invalidation** inside `build_graph()` — warm-path calls no longer rebuild the palace-graph per request. (#661)
+- **`mempalace init` entity detection overhaul.** Canonical project names now come from package manifests (`package.json`, `pyproject.toml`, `Cargo.toml`, `go.mod`) and real people come from git commit authors, rather than being inferred from prose. Includes union-find dedup across name/email aliases, bot filtering that keeps `@users.noreply.github.com` humans, and automatic "mine" flagging by contribution share. (#1148)
+- **Regex detector accuracy.** CamelCase extraction so `MemPalace`, `ChromaDB`, `OpenAI` aren't fragmented; tighter versioned/hyphenated pattern kills `context-manager` / `multi-word` false positives; dialogue `^NAME:\s` requires ≥2 hits so `Created: <date>` metadata stops classifying field names as people; expanded stopwords for common English participles and descriptors; high-pronoun signal classifies as person rather than dumping to uncertain. (#1148)
+- **Init → miner wire-up.** Confirmed entities merge into `~/.mempalace/known_entities.json` on init, which the miner reads to tag drawer metadata for entity-filtered search. Previously init's output was not consumed by the miner; the per-project `entities.json` is kept as an audit trail. (#1157)
+- **Case-insensitive project dedup** across manifest, git, and convo sources so casing variants of the same project name collapse into one review entry. (#1175)
 
 ### Added
 
 - i18n: Belarusian translation. (#1051)
 - i18n: entity detection for German, Spanish, and French locales. (#1001)
 - i18n: Traditional + Simplified Chinese entity detection. (#945)
+- **`mempalace init --llm`**: optional LLM-assisted entity classification. Defaults to local Ollama (zero-API); also supports any OpenAI-compatible endpoint (LM Studio, llama.cpp server, vLLM, OpenRouter, etc.) and the Anthropic Messages API. Runs interactively with a progress indicator; Ctrl-C cancels cleanly and returns partial results. Useful for prose-heavy folders where the regex detector struggles (diaries, transcripts, research notes). Opt-in only — default init path remains zero-API. (#1150)
+- **Claude Code conversation scanner.** `~/.claude/projects/<slug>/` directories now contribute project entities using each session's authoritative `cwd` metadata, avoiding slug-decoding ambiguity. (#1150)
 
 ### Known — deferred to v3.3.4
