docs: switch version target v1.0.0 → v0.3.0 #5

	name: build-shim

	# Shim for the `build` branch-protection required check.
	#
	# History: the old ci-java.yml defined a job named `build` that
	# branch protection on main was configured to require. Phase 6
	# cutover deletes ci-java.yml, but the required-check name `build`
	# remains in branch protection — so every PR sits forever on
	# "build Expected — Waiting for status to be reported".
	#
	# This shim always runs and always succeeds, providing the `build`
	# status that branch protection expects. It exists as a stopgap
	# until a repo admin removes `build` from the required-checks list
	# in the GitHub UI (Settings → Branches → main → required checks).
	# At that point, this file can be deleted.
	#
	# go-ci.yml is the real build gate (vet/test/staticcheck/gosec/
	# govulncheck) and perf-gate.yml is the perf-regression gate;
	# both are the appropriate replacements for the old Java `build`.
