feat(debug): expose @debug.to_string under the shorter prelude name `repr`

Adds `#alias(repr)` to `@debug.to_string` so it can also be called as
`@debug.repr`. Re-exports `repr` from prelude alongside `to_repr`, so
user code can write `repr(x)` for a one-step Debug rendering with no
imports needed. Same underlying function as `@debug.to_string`; pick
whichever name reads better at the call site.

The deprecated `@builtin.repr` (Show-based) is kept for callers using
the qualified spelling, but is no longer re-exported from prelude — the
unqualified `repr` now resolves to the Debug-based function. The
deprecation message is updated to point at `@debug.repr` / prelude
`repr` instead of `to_repr` (which returns a `Repr`, not a `String`).

This is a deliberate semantic flip for unqualified `repr(x)`: it now
returns the Debug rendering (strings quoted, tuples / arrays
structural). The old Show-based behavior remains available through the
deprecated `@builtin.repr(x)` qualified spelling and via the value's
`to_string()` method.

Verified:
- `repr("hi") == "\"hi\""`, `repr('a') == "'a'"`, structural rendering
  for tuples/arrays
- `@debug.repr == @debug.to_string` (alias resolution)
- prelude resolution of unqualified `repr`
- full test suite passes on wasm, wasm-gc, js, native (6386-6475 tests
  per target)
