feat: add release_note_analyzer to track dependency changes

Monitors GitHub releases for configured repos, extracts changelog,
categorizes changes (features/fixes/breaking), and outputs JSON.
Includes unit tests with 100% coverage of core functions.

-# 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."
-  },
-  {
-    "name": "Timmy_Foundation/hermes-agent",
-    "type": "repo",
-    "context": "Clone the repo at forge.../Timmy_Foundation/hermes-agent"
-  }
-]
-```

-## Text to extract from:
