v0.2.3

• Added immutable target profiles for architecture, ABI, endianness, scalar/vector features, and vector-width policy.
• Added bounded 8/16/32/64-bit Word memory to both IR forms with explicit regions, alignment, byte order, and diagnosed exits.
• Added Float32/Float64 memory, exact byte reversal, signed-zero preservation, and cross-endian differential tests.
• Added zero-initialized non-addressable Word/Float64 frame locals with typed access and sensitive-slot clearing.
• Added invocation-bound trusted object layouts with semantic identities, fixed fields, permission preflight, and managed entry.
• Documented the independent commercial roadmap after auditing SLJIT only as a capability reference.
• Expanded real-host, sanitizer, package, negative-verifier, and resource-limit qualification for the new provenance model.
• Added the repository-level MIT License.
