feat(extract): Chunk-Ausgabe, Manifest und Ablaufsteuerung

Task 6: leonida/emit.py (chunk_box, split_by_chunk, chunk_payload und die
Chunk-lokalen three.js-Koordinaten, write_chunks, write_debug_png) sowie
run.py als Ablaufsteuerung, die alles aus den Tasks 3-5 zu 144 Chunk-Dateien
und einem Manifest unter public/data/vice-a/ zusammenfuehrt.

Zwei Abweichungen vom Referenzcode der Aufgabe, beide durch Gegenrechnen
gegen die dort genannten Realwerte gefunden:

- test_emit.py::test_coordinates_are_chunk_local_three_js gab im Original
  das ungeschnittene BIG (spannt vier Chunks) direkt an chunk_payload();
  chunk_payload() clippt selbst nicht (das tut in run.py split_by_chunk_all
  vorher), darum lag der Rand bei x=300 statt <=250 und der Test schlug mit
  dem gegebenen Code fehl. Fix: BIG vor dem Aufruf mit split_by_chunk auf
  Chunk (0,0) zuschneiden, wie es run.py fuer "land" ohnehin tut.

- run.pys Filter "Gebaeude, die zu >50% in einem Strassenpolygon liegen,
  gelten als Strasse" pruefte im Original ALLE rohen Gebaeude gegen
  road_polygons(labels) direkt. road_polygons() zaehlt "spekulativ" selbst
  zu den Strassenklassen (ROAD_CLASSES) und schliesst zusaetzlich mit
  disk(3) gegen Strassennamen; ein isoliertes "spekulativ"-Gebaeude
  ueberlappt sich darueber praktisch mit sich selbst. Ergebnis am realen
  Mosaik: von 267 rohen spekulativen Gebaeuden ueberlebten nur 3 (statt der
  in der Aufgabe genannten Groessenordnung von 258), und die Schliessung
  riss zusaetzlich 211 gewoehnliche graue Gebaeude mit heraus, die die
  Notiz aus Task 5 ausdruecklich nicht meinte ("die ROTEN Flaechen ...
  werden abgezogen"). Fix: eigenes, unzweideutiges Strassenmass nur aus
  "strasse"/"weg" (ohne "spekulativ", ohne Namens-Schliessung), Pruefung
  nur auf spekulative Kandidaten begrenzt. Ergebnis: 2.348 Gebaeude, davon
  263 spekulativ (Aufgabe: 2.352 bzw. 258) - Wahrzeichenhoehen (68 Stueck,
  31-248 m) und Palmenzahl (2.133) treffen die genannten Referenzwerte exakt.

Pipeline-Lauf am gecachten Mosaik: 144 Chunk-Dateien + Manifest, 2,5 MB
gesamt (Budget 10 MB), groesste Datei chunk_9_1.json/chunk_10_1.json mit
je 40 KB. Alle drei Toleranzgrenzen (wasser/strasse/gebaeude) eingehalten.
Debug-PNGs stichprobenartig gesichtet: Kuestenlinie, Strassennetz
(inklusive Kreuzungen und einer Auffahrt-Rampe) und ein Strand mit
Palmenreihe liegen deckungsgleich auf dem Mosaik; der wasserreine Chunk
(4,10) zeigt korrekt keine Vektoren.
