AIGX 1.3.0 — editor support + interactive scaffolding

Phase 4: editors recognize .aigx, and adoption becomes delightful. The specification version stays
1.1 — this is an editor + tooling release.

Editor support

• VS Code — "AIGX Language Support" (editors/vscode):
  syntax highlighting, file icons (.aigx + protocol/files/architecture/product/testing.aigx) and an
  optional icon theme, snippets, tag + rule-id autocomplete inside <check>, hover on rule ids,
  go-to rule definition, inline diagnostics (the same checks as aigx-lint), formatting, and
  AIGX: Resolve current file's boundary. Self-contained — no npm runtime dependencies.
• Canonical TextMate grammar (editors/textmate):
  one source.aigx grammar reused across VS Code, GitHub Linguist, Zed, Sublime Text, TextMate, Cursor, Windsurf.

A world-class adoption kit

• npx create-aigx is now interactive — pick your agent(s) (Cursor · Claude Code · Copilot · Windsurf ·
  Aider · generic AGENTS.md), choose CI, and watch a gradient scaffold confirm every file. Per-agent flags
  (--cursor …), --yes, --aigx-only, --no-ci, and a non-interactive fallback keep automation happy.
• aigx init reaches parity — the same interactive agent selection with embedded integrations, fully
  self-contained.
• New integration templates: aider.conf.yml and a generic AGENTS.md.
