Guard deep link map parser against OOM via oversized input

[Copilot]

Crafted roboyard://open?data=... deep links with arbitrarily large board dimensions or excessive robot/target counts could cause an OutOfMemoryError in convertWebFormatToAppFormat — a remote denial-of-service with no user interaction required.

Changes

MainActivity.java

• Added size-limit constants:

  private static final int DEEPLINK_MAX_WIDTH   = 200;
  private static final int DEEPLINK_MAX_HEIGHT  = 200;
  private static final int DEEPLINK_MAX_CELLS   = 40_000;
  private static final int DEEPLINK_MAX_ROBOTS  = 50;
  private static final int DEEPLINK_MAX_TARGETS = 50;

• Validate width, height, and width × height before allocating the grid; return null immediately on violation
• Robot/target collection loops now return null as soon as the count exceeds its limit (fail-fast — no list over-allocation)
• handleIntent handles the null return: shows a localized Toast and drops the deep link silently

String resources

• Added deeplink_map_too_large to all 9 language files (en, de, es, fr, ko, ja, zh, pl, pt-rBR)
