Adds a new MCP tool `search_decisive_appraisals` that queries the
Ministry of Justice public registry (~30K published decisions) by
block (גוש), plot (חלקה), appraiser name, committee, decision/publicity
date ranges, or free text — and returns metadata + direct PDF URLs.
Implementation notes:
- New `nadlan_mcp/govil/` package, parallel to `nadlan_mcp/govmap/`,
for gov.il APIs that are not Govmap. Pydantic v2 models match the
upstream PascalCase response via aliases.
- Upstream sits behind an F5 WAF that rejects standard `requests`;
uses `curl_cffi` with Chrome 120 impersonation to traverse it.
- Static `x-client-id` header (issued to the gov.il SPA, public, visible
in any DevTools session) is required by the gateway — without it
every call returns a generic 500.
- 14 unit tests cover model parsing, body shape, pagination, and the
500-is-fatal contract (configuration error, not retryable).
