feat: add entity_extractor for NER (8.1 Entity Extractor)

Add scripts/entity_extractor.py — LLM-based named entity recognition from session transcripts, READMEs, and issues. Extracts people, projects, tools, concepts, and repos. Outputs to knowledge/entities.json.

Includes:
- templates/entity-extraction-prompt.md — extraction prompt
- tests/test_entity_extractor.py — unit tests for dedup/merge logic
- scripts/test_entity_extractor.py — smoke test (mocked pipeline)

Accepts --file, --dir, --session, --batch modes. Deduplicates by name+type, merges with existing entities.json. Designed to yield 100+ entities per batch run.

Closes #144

+# Entity Extraction Prompt
+
+## System Prompt
+You are an entity extraction engine. You read text and output ONLY a JSON array of named entities. You do not infer. You extract only what the text explicitly mentions.
+
+## Task
+Extract all named entities from the provided text. Categorize each entity into exactly one of these types:
+- `person` — individual's name (e.g., Alexander, Rockachopa, Allegro)
+- `project` — software project or component name (e.g., The Nexus, Timmy Home, compounding-intelligence)
+- `tool` — software tool, command, library, framework (e.g., git, Docker, PyTorch, Hermes)
+- `concept` — abstract idea, methodology, paradigm (e.g., compounding intelligence, bootstrap, harvester)
+- `repo` — repository reference in the form `owner/repo` or URL pointing to a repo
+
+## Rules
+1. Extract ONLY names that appear explicitly in the text.
+2. Do NOT infer, assume, or hallucinate.
+3. Each entity must have: `name` (exact string), `type` (one of the five above), and `context` (short snippet showing usage, 1-2 sentences).
+4. The same entity mentioned multiple times should appear only ONCE in the output (deduplicate by name+type).
+5. For `repo` type, match patterns like `owner/repo`, `github.com/owner/repo`, `forge.alexanderwhitestone.com/owner/repo`.
+6. For `tool` type, include commands (git, pytest), platforms (Linux, macOS), runtimes (Python, Node.js), and CLI utilities.
+7. For `person` type, look for capitalized full names, or single names used in personal attribution ("asked Alex", "for Alexander").
+8. For `concept`, include technical terms that represent an idea rather than a concrete thing.
+
+## Output Format
+Return ONLY valid JSON, no markdown, no explanation. Array of objects:
+```json
+[
+  {
+    "name": "Hermes",
+    "type": "tool",
+    "context": "Hermes agent uses the tools tool to execute commands."
+  },
+  {

+    "context": "Clone the repo at forge.../Timmy_Foundation/hermes-agent"
