Re-applies commit 1120b9084e (reverted in ef2c1d47cc during install
debugging). The install failure was proven to be the oversized watch
binary (fixed by DEAD_CODE_STRIPPING), not the bundle-id mechanism — which
was verified to produce a byte-identical artifact for ph.telegra.Telegraph.
xcodebuild bakes PRODUCT_BUNDLE_IDENTIFIER=<host>.watchkitapp and the watch
Info.plist derives WKCompanionAppBundleIdentifier via
$(PRODUCT_BUNDLE_IDENTIFIER:base), so the embedded watch app is correct for
any host (ph.telegra.Telegraph and org.telegram.TelegramInternal/enterprise)
with no post-build plist patching.
