feat(web): configurable Sentry crash tracking + runtime client config #38

	name: Docs CI

	# Builds the docs site on PRs that touch docs/. The Astro build runs
	# starlight-links-validator, so broken internal links fail the check.
	# The job always runs (so it can be a required status check) but only does
	# work when docs/ actually changed.
