Norm 0.8

Norm 0.8 completes the vertical implementation of user-defined values.

Language

value is contextual only in a top-level declaration header;
values support fields, methods, generics, and interface conformance;
value fields cannot be assigned after construction;
assignment, parameter passing, returns, and field reads preserve logical independence;
equality and hash recursively use language field semantics, allowing values as Map keys and Set elements.

SemanticModel carries the value category;
Core definitions, namespace ABI, and runtime types preserve the same category;
Core identity advances to Schema V4 and Language Semantics V4;
Truffle centralizes copying, equality, and hash behavior;
the formatter, language server, single-file programs, and cross-package projects share the same declaration and type model;
project loading, module graphs, and standard-library bootstrap share typed module descriptors across the CLI, language server, and runtime;
local VS Code packages and release packages use the same release-target manifest and acceptance entrypoints.
