Shared lang-map module in @refrakt-md/runes

Add a small extension-to-language map at packages/runes/src/lang-map.ts, exported from @refrakt-md/runes. Consumers (the snippet rune from WORK-255, the inspect tool in packages/cli/, the contracts generator, future runes wanting extension inference) import from there.

Living in @refrakt-md/runes rather than a plugin or the transform package is deliberate: every consumer already depends on runes; plugins can import from runes but not the reverse; and it's rune-shaped knowledge, sitting alongside the existing rune-utility surface.

Acceptance Criteria

  • packages/runes/src/lang-map.ts exists and is exported from the package's index
  • Map covers the extensions documented in SPEC-062 Language Inference: .ts, .tsx, .js, .jsx, .mjs, .cjs, .svelte, .vue, .md, .markdoc, .json, .jsonc, .html, .css, .yml, .yaml, .toml, .sh, .bash (extensible)
  • Unknown extensions fall back to "text" (no highlighting)
  • Exported as both the raw map and a helper function (e.g., inferLanguage(path: string): string) for ergonomic use
  • Unit tests cover the documented mappings and the fallback case
  • Type definitions exported

Approach

Tiny module: a Record<string, string> plus a helper. Both exported from @refrakt-md/runes. The helper takes a file path or extension and returns the language string (defaulting to "text"). No external dependencies.

Dependencies

  • None within v0.15.0. Independent.
