android: V4.9 + V4.10 Kotlin ports + KeystoreStorage adapter
Pure-JVM additions to shade-android (no Android SDK needed):
- V4.9 blob primitives: BlobKdf (HKDF deriveBlobSlotId/Key/SigningSeed),
  BlobAead (nonce||ct||tag with shade-profile-aad-v1:<slot> AAD),
  BlobClient (java.net.http with hand-written canonical JSON signing
  matching TS signPayload output), Profile high-level namespace.
- V4.10 approval helpers: CanonicalProfileBlob schema with denormalized
  trustedApproverFingerprints, build/sign/verify proxy approvals via
  length-prefixed u16 BE UTF-8 canonical signing payload.
- Password KDFs: scrypt + argon2id via Bouncy Castle, NFKC-normalized.
- SessionStateJson at-rest serializer for persistence layer.

Cross-platform vectors (test-vectors/blob.json, approval.json) gate
byte-identical output between TS and Kotlin, including a TS-signed
Ed25519 signature the Kotlin port verifies and reproduces (Ed25519 is
deterministic).

New shade-android-keystore sibling Gradle module (Android-specific):
- KeystoreMasterKey: hardware-backed AES-256-GCM with BIOMETRIC_STRONG
  gating, StrongBox-backed when available, invalidated on enrollment.
- BiometricUnlock: coroutine wrapper around BiometricPrompt with
  tagged cancellation/failure exceptions.
- KeystoreStorage: StorageProvider over biometric-gated AES-encrypted
  SharedPreferences with AAD-bound row keys.

All 25 SDK packages typecheck clean; 104 SDK tests + 24 new Kotlin
tests + 11 cross-platform vector tests all green.

// is JVM-safe (no `android.*` imports); only Tink + java.* are used.
//
// When KeystoreStorage and EncryptedSharedPreferences-backed adapters land
// (M-Cross 4 + V3.5 §Storage), they will live in a sibling Android Library
// module that depends on this one.
