BioLang v0.4.0

BioLang v0.4.0

Editor tooling release: the VSCode extension gains a document formatter,
plus housekeeping (all commit messages are now in English; the contributor
list is cleaned up).

What's new since v0.3.0

• VSCode extension formatter (extension v0.16.0) — a built-in
  DocumentFormattingProvider for .bio / .bl files (Shift+Alt+F):
  • 4-space indentation with block tracking (including one-line blocks and
    } else {);
  • spaces around binary operators, after commas and if/while/for;
  • strings, characters and comments are passed through untouched —
    formatting never changes program semantics;
  • verified: all 17 examples are idempotent under formatting and produce
    byte-identical interpreter output after formatting.
  • New module: vscode/biolang-vscode/src/formatter.js.
• Housekeeping — all commit messages in English; Co-Authored-By
  trailers from the earlier Claude Code era removed from history; AGENTS.md
  untracked; contributor statistics refreshed (may take GitHub a while to
  reflect).

Each package contains a launcher (bin/bio or bin/bio.bat) and the shared
runtime in lib/ (libbio.so / libbio.dylib / bio.dll). The LLVM backend
(bio llvm) is built from source with make bio-llvm (requires LLVM).

Known limitations

• Threadstream / Areastream not yet declarable as explicit stream types.
• LLVM backend stage 3 (streams/classes/needs/smart refs/phone booths) is
  future work.
• Windows/macOS Apple Silicon are experimental (see Platform support).
