fix: numeric skill names, ultrawork missing run_in_background, ZWSP agent lookups

- #3354: Coerce data.name to String in loadSkillFromPath/loadSkillFromPathAsync
  to prevent crash when YAML parses numeric skill names (e.g., name: 12306)

- #3416: Add required run_in_background parameter to all task() examples in
  ultrawork prompts (default, gpt, gemini, planner) to match tool schema

- #3379/#3417/#3418/#3337/#3335: Strip ZWSP (U+200B) before agent name
  comparisons in agent-tool-restrictions, sync-prompt-sender, tool-execute-after,
  tool-execute-before, oracle-verification-detector, call-omo-agent,
  recovery-prompt-config, and agent-variant to prevent ZWSP-prefixed display
  names from breaking exact-match lookups
