fix(ci/release): archive unsigned + codesign Developer ID directly

xcodebuild's archive gate demands a provisioning profile for the app's
keychain-access-groups entitlement (the 'Keychain Sharing' capability) under
both automatic AND manual signing — even though a Developer ID app honours that
team-prefixed entitlement at runtime with no profile. So manual signing just
traded the -61 keychain error for 'requires a provisioning profile'.

Sidestep the gate: archive with CODE_SIGNING_ALLOWED=NO, then codesign the app
bundle directly with the Developer ID identity, hardened runtime and a secure
timestamp, applying the entitlements via --entitlements (with $(AppIdentifierPrefix)
resolved to the team prefix, which codesign won't expand). Safe because the
bundle is a single statically-linked binary — static PunktfunkCore.xcframework,
SPM static products, macOS 14 target, no Embed-Frameworks phase — so there is no
nested code to sign inside-out. No Apple Developer portal profile or new secret
needed. iOS App Store path unchanged.
