fix: Claude multiline suggestion placement #800

	# XcodeGen drift gate.
	#
	# The .xcodeproj is generated from `project.yml` but committed to the repo so
	# contributors can `open Cotabby.xcodeproj` without installing XcodeGen first.
	# That convenience only holds if the committed project stays byte-identical to
	# what `xcodegen generate` produces. This job regenerates on every PR and fails
	# if the result differs from what's checked in — catching the case where
	# someone edits the project in Xcode (or hand-edits the pbxproj) without
	# mirroring the change into `project.yml`.
	#
	# Sibling to Build/Lint/Tests: one gate, one file, one clear failure mode.
