Module inline_function 

Inline-function recipe: replace a single-use function’s call site with its body.

Steps:

1. Locate the function definition at the given position (line:col may point to the function name in the definition or in a call site)
2. Find all call sites of this function within the same file (name-match)
3. Verify the function is called exactly once (or --force to override)
4. Substitute arguments for parameters throughout the body
5. Replace the call expression with the inlined body
6. Remove the function definition

Supported languages: JavaScript, TypeScript (function declarations, arrow-function const bindings). Python (def) and Rust (fn) are structurally similar but less tested.

Conservative: aborts rather than generating broken code.

• Multiple return statements → error
• Non-trivial control flow → error
• Grammar unavailable → error
