feat: standards, shared CI and release tooling for NAPALM drivers

STANDARDS.md binds every repository in the NAPALM org: one default branch,
Conventional Commits, the device-types contract, test-driven development,
clean-code limits, a quality ratchet for existing code, packaging rules and
releases by tag to PyPI.

napalm-standard holds what a tool can check: the conformance check (with
release rules on a tag), the quality ratchet (ported from netOrk's
quality_ratchet.py), and the Gitea release from the CHANGELOG section.
.gitea/workflows/driver.yml is the CI every driver calls; template/ is a new
driver's starting point and passes the check as it is.
