Remove request dependency

[jeffutter]

Besides being depreciated in 2020, request has some transitive dependencies that I think might be polluting the claude context window a bit.

{
  "type": "progress",
  "data": {
    "type": "hook_progress",
    "hookEvent": "PostToolUse",
    "hookName": "PostToolUse:Glob",
    "command": "${CLAUDE_PLUGIN_ROOT}/scripts/run"
  },
  "parentToolUseID": "toolu_01274ZmywfpAv6SpnGs3U4TN",
  "toolUseID": "toolu_01274ZmywfpAv6SpnGs3U4TN",
  "timestamp": "2026-01-19T12:24:47.591Z",
  "uuid": "5e0363fa-ff69-475c-895f-ac20ec7015cf"
}
{
  "attachment": {
    "type": "hook_success",
    "hookName": "PostToolUse:Glob",
    "toolUseID": "toolu_01274ZmywfpAv6SpnGs3U4TN",
    "hookEvent": "PostToolUse",
    "content": "",
    "stdout": "",
    "stderr": "(node:1279458) [DEP0040] DeprecationWarning: The `punycode` module is deprecated. Please use a userland alternative instead.\n(Use `node --trace-deprecation ...` to show where the warning was created)\n",
    "exitCode": 0
  },
  "type": "attachment",
  "uuid": "ced081c8-1833-434c-978e-35abeef6c8c5",
  "timestamp": "2026-01-19T12:24:47.856Z"
}

I'm not actually sure if that stderr output gets fed back to claude, but punycode is a transitive dependency of request.
