v1.7.0

v1.7.0 — 2026-09-10

Minor release. Migrates the HTTP stack from httpx to Pydantic's maintained
httpx2 fork, and keeps httpx2 off the nsc --help cold-start path. No
user-facing CLI or behavior changes.

Changed

• Migrated the HTTP stack from httpx to httpx2 (#146). httpx2 is
  Pydantic's stewardship continuation of httpx (same author, API-identical) —
  httpx itself has seen limited activity, and httpx2 is the reliably-maintained
  path forward with timely security updates. The dependency floor is now
  httpx2>=2.5; the source layer is a mechanical rename (import httpx2,
  httpx2.Client/httpx2.Response/…). Test mocking moves from global respx
  to the pytest-httpx2 plugin's httpx2_mock fixture (a respx.Router, by
  respx's own author), which targets httpx2's httpcore2 transport. No
  user-facing behavior or CLI surface changes.
• httpx2 is now kept off the nsc --help / cold-start path (#13). httpx2 is
  the single heaviest import in the tree (~65ms cold), and nothing on the startup
  path needs an HTTP client. It was being pulled in eagerly through the
  runtime → client → retry chain (plus cache, schema, and login
  command modules). All of these now import httpx2 lazily, at first request. Cold
  startup drops by roughly httpx2's import cost, bringing the median back under the
  300ms project target. A new guard test (test_lazy_httpx2_import.py) asserts
  httpx2 never loads on nsc --help, and the startup benchmark's threshold is
  re-baselined to 300ms so an over-threshold skip once again signals a real
  regression instead of firing on every run.
