MiniLang Compiler 1.2.1

MiniLang Compiler 1.2.1

MiniLang 1.2.1 is a source-only maintenance release of the matching Python
reference and self-hosted compilers. Generated executables remain excluded from
Git and from GitHub release assets; the native compilers are rebuilt and
verified from the tagged sources.

Highlights:

• explicit /// declaration comments in both compiler frontends, kept outside
  the runtime AST and generated program;
• complete English declaration documentation for the shared standard library
  and the self-hosted compiler implementation;
• strict MiniDoc configurations and committed HTML and GitHub-compatible
  Markdown API references;
• the synchronization, native timeout, Linux FFI, socket, project-cache,
  assembler, GC and thread-lifecycle hardening accumulated since 1.2.0; and
• unchanged Windows x64 PE32+ and Linux x64 ELF64 target compatibility between
  the Python and self-hosted compilers.

The acceptance build verifies both compiler suites, strict warning-free MiniDoc
generation, byte-identical shared standard-library sources and documentation,
Windows fixed-point self-hosting, and a native Linux MiniDoc build and test run.
