Commit Message

refactor(bigint)!: promote `shl`/`shr`, drop `asr`/`lsl`

`BigInt::shl` and `BigInt::shr` were hand-written deprecated wrappers that just
forwarded to `<<` / `>>`. Per AGENTS.md the shift operators are promoted on
every type, so replace both with `pub extend BigInt with Shl::{shl}` /
`Shr::{shr}` in `extends.mbt`, alongside the other operator promotions. Their
signatures are unchanged (`(Self, Int) -> Self`); they simply stop warning.

`BigInt::asr` and `BigInt::lsl` have no trait to promote to — `>>` and `<<` are
spelled `Shr::shr` / `Shl::shl` — so they are removed rather than kept as
wrappers.

The promotions go in `extends.mbt`, not `deprecated.mbt`: they are blessed
public API, matching `int16/extends.mbt` and `builtin/extends.mbt`. Placement is
interface-neutral — `bigint/pkg.generated.mbti` is identical either way.

BREAKING CHANGE: `BigInt::asr` and `BigInt::lsl` are removed. Use `>>` and `<<`.

No references to either remain in core.
