chore: clean .gitignore (utf-16 noise) + mark plan 005 shipped

- .gitignore had 2 lines saved as UTF-16-LE (temp-db-check.cjs and
  .playwright-mcp), so the patterns weren't actually ignoring those
  files. Rewrote in plain UTF-8.
- Plan 005 (gis-api export endpoints) was marked "not yet built" but
  gis-api commit bbd6e7c shipped all five endpoints on 2026-05-21 with
  38 new tests; update the status block to reflect that, including the
  one open caveat (PIZ basemap=orto still 501).

 # Plan 005 — gis-api export endpoints (PIZ / PAD / Coord / DXF / CF intern)
 
-**Date:** 2026-05-21
+**Date:** 2026-05-21 (updated 2026-05-27)
 **Author:** ArchiTools session (V2 panel toolbar)
 **Owner of execution:** gis-api session (`/home/orchestrator/Code/gis-api`)
-**Status:** Architots side complete; gis-api endpoints not yet built.
+**Status:** SHIPPED — gis-api commit `bbd6e7c` (2026-05-21) added all five
+endpoints (`/parcel/:id/{piz,pad,coords-xlsx,dxf}` + `/enrichment/cf-intern`)
+with 38 new tests. PIZ basemap=orto still returns 501 awaiting an
+orchestrator basemap proxy; arch UI disables that button (commit `5cfa6c8`).
+Architools toolbar is fully functional for all four exports via the default
+basemap. CF intern works end-to-end (verified live with curl + DB rows from
+2026-05-23/24).
