* fix: harden package URL downloads
Guard package acceptance URL downloads with HTTPS-only validation, no embedded credentials, private/special-use DNS and IP rejection, manual redirect checks, bounded timeout/size limits, pinned lookup, and atomic temp-file writes. Add tooling tests for unsafe URLs, redirect validation, size limits, and successful writes.
* fix: cancel redirect response bodies before closing dispatcher
ClawSweeper P2: the redirect branch in openPackageDownloadResponse cleared
the timeout and awaited dispatcher.close() without first cancelling
response.body. Undici's close() is graceful — it waits for in-flight
requests to complete — so a malicious redirect with a slow/never-ending
body could hang the hardened downloader.
Fix: call response.body?.cancel() before dispatcher.close() to abort the
redirect body immediately.
Test: add a regression test that uses a ReadableStream with an indefinite
interval to simulate a hanging body, and asserts cancel() was called.

* test: harden redirect body cancellation race in regression test
Guard the ReadableStream controller.enqueue() call with a cancelled
flag and try/catch to prevent ERR_INVALID_STATE when the interval
fires after cancel() closes the controller.
* fix: cancel final response body before closing dispatcher in downloadUrl
ClawSweeper P2: the HTTP-error and declared-oversize early-exit paths
in downloadUrl threw before consuming or canceling response.body. The
finally block then cleared the timeout and awaited graceful
dispatcher.close() with the body still open, allowing a slow/never-ending
response to hang release tooling.
Fix: add response.body?.cancel() in the finally block before
dispatcher.close().
Tests: add two regressions:
- HTTP 500 with slow body: asserts cancel() called before dispatcher close
- Declared content-length oversize with slow body: same assertion
