Bug Fixes

• cleanup: Activate signal/atexit handlers on the calling thread for adopted and remote ops (06cc519)

Move cleanup-handler activation into a dedicated Session._activate_cleanup_handlers() helper. Call it from Session.from_id(adopt=True), Session.list(adopt=True), and RemoteFunction.remote() before dispatching async work.

This installs process-wide SIGINT/SIGTERM and atexit hooks on the thread that requests ownership, rather than only when a sandbox is constructed.

Add unit tests for from_id(adopt=True) and RemoteFunction.remote().

• cleanup: Install atexit and signal handlers lazily on first owned sandbox (e515aff)

import cwsandbox no longer registers process-wide SIGINT/SIGTERM handlers. Cleanup hooks now activate the first time a standalone Sandbox is constructed or a Session owns or adopts a sandbox. Worker-thread imports no longer raise ValueError.

Fixes #136

Chores

• proto: Regenerate stubs and map dns_name to https_hostname (7b2da11)

Vendors the latest v1 consumer stubs and remaps public EgressRule.dns_name onto the renamed wire field so create/echo keep working.

Testing

• cleanup: Add bounded fresh-process SIGTERM helper and deduplicate tests (3d8d065)
