## Description The `Repr` type name was unclear — it was intended to represent a lambda calculus expression, not a "representation." This PR renames `Repr` to `Expr` throughout the registry package for clarity. - Rename `Repr` interface to `Expr` and `baseRepr` struct to `baseExpr`. - Rename `repr.go` to `expr.go`. - Rename `ID()` method to `Repr()` to indicate the representation type. - Rename `NewRepr` constructor to `NewExpr`. - Update all usages in codec, conversion, engine, process, and registry files. - Add command aliases `conv` and `eng` for `convert` and `engine` subcommands. ## Benefits - The naming better reflects the domain: an `Expr` is an expression, and `Repr()` returns its representation kind. - Command aliases reduce typing for common subcommands. ## Checklist - [x] Code follows conventional commit format. - [x] Branch follows naming convention (`<type>/<description>`). Always use underscores. - [x] Tests pass (if applicable). - [x] Documentation updated (if applicable). Reviewed-on: #44 Co-authored-by: M.V. Hutz <git@maximhutz.me> Co-committed-by: M.V.
