Dominik Roth 1ddb532325 Fix ally/target bugs, OCR fire-support parsing, add debug capture
- Board.clear() now also drops allies; the "clear board?" guard checks
  allies too. New Board.clear_units() + Clear button right-click menu
  ("clear enemies, units & flights", keeps Nest/spotters/RPs).
- An Ally with the ad-hoc TargetType.ENEMY showed "Enemy" on the map
  popover/toast instead of "Ally" (icons.target_type_label already had
  the fix for the picker, now reused everywhere else via app.py's
  _display_name).
- Firing panel drag-reorder no longer triggers a full app refresh
  (solver + dedupe + map redraw) on every drop, just a local rebuild.
- "Always show geo" didn't draw for Allies (missing from the overlay
  candidate list); blast radius only respected selection, not the
  show_geo_desc pin.
- ocr.py: added a second fire-support-request grammar ("Infantry#N
  taking fire ... Requesting X Shell on our position at <coord> before
  <time>", plus a bearing/distance-from-position variant), distinct
  from the existing Marine Garrison one.
- New debug_capture.py: saves screenshots (+ metadata) the app handled
  badly, for later tuning of map_vision/ocr against real failures:
  map-read errors, user grid corrections (paired with the auto-detected
  grid), screenshots that read as text but may have been a map, and
  marker-detection ground truth (every proposal's accept/reject verdict
  plus units added with no matching proposal) captured whenever a
  screenshot stops being the active one.
- README: Known issues section (map screenshot reading, grid + unit
  detection, is unreliable and fails often).
- 14 new tests (tests/test_models.py, tests/test_debug_capture.py, +
  additions to tests/test_ocr.py), 38/38 passing.

"""Regression coverage for every intel-text format ocr.py understands.
Each format below was added incrementally in response to a real
screenshot/paste the user hit, and at least one of them (the '<ref>:
<value>' grammar colliding with the 'Type#id:' header shape) has already
regressed silently once because there was no test suite to catch it.
One test per format, named after what it covers, so a future change
that breaks an old format fails loudly and specifically instead of
being noticed (or not) days later.
