[Bug] Tool use rejection causes infinite hang instead of error message

Bug Description
I am trying to explicitly use a skill and opus 4.7 is blocking it but telling me that I am blocking it, so it results in it hanging forever until I kill it and ask it to tell me what was wrong:

❯ ask codex "ping"

⏺ Skill(codex:rescue)
  ⎿  Done

⏺

⏺ Skill(codex:rescue)

❯ were you able to use those skills?

⏺ Partially. The codex:rescue skill loaded and prompted me for a task, but when I tried to re-invoke it with the "ping" payload, you rejected the tool call — so no Codex
  round-trip happened.

  Want me to retry, or run it differently?
