burnie-updatelisted

Fetch current Claude model prices from anthropic.com/pricing and update `src/burnie/pricing.py`. ## Steps 1. Fetch https://www.anthropic.com/pricing with WebFetch 2. Extract the $/MTok prices for each model family (input, output, cache write, cache read) 3. Update `src/burnie/pricing.py`: - Replace the `PRICING` list entries with the new values - Update `PRICING_UPDATED` to today's date (YYYY-MM-DD format) 4. If any price actually changed (not just `PRICING_UPDATED`), bump the version to prepare a release: - Bump the patch version in `pyproject.toml`'s `version` - Bump `metadata.version` in `skills/burnie/SKILL.md` and `skills/burnie-update/SKILL.md` to match - All three must stay in sync, same as a manual release bump 5. Report what changed (which models, old vs new values, and the new version if bumped) ## Notes - Cache write is typically 1.25× input price - Cache read is typically 0.1× input price - If a model from the current list is no longer on the pricing page, keep it but add a comment `# discontinued?` - If a new model appears, add it following the same format - Only edit `src/burnie/pricing.py` for pricing data. The other files import from it - If no prices changed (only `PRICING_UPDATED` moved, or nothing moved at all), don't bump the version
