Subagents don't respect Write(*)/Edit(*) allow rules or acceptEdits defaultMode

Description

Subagents (spawned via the Agent tool) still prompt for file creation/edit permission even when the parent session's settings explicitly allow all writes and edits.

Settings

{
  "permissions": {
    "allow": [
      "Write(*)",
      "Edit(*)"
    ],
    "defaultMode": "acceptEdits"
  }
}

These are in ~/.claude/settings.json (user-level settings).

Expected behavior

Subagents should respect the same permission allow rules and defaultMode as the parent session. File writes/edits should be auto-approved without prompting.

Actual behavior

Subagents show the 3-option permission prompt for every file creation:

Create file src/Example/NewFile.cs
 Do you want to create NewFile.cs?
 ❯ 1. Yes
   2. Yes, allow all edits during this session (shift+tab)
   3. No
