Commit Message

refactor(error): drop the catch-all cleanup in the protect design notes

The pre-release compiler's new `fragile_catch_all` lint (error 0092) rejects a
catch-all whose handler cleans up and re-raises, which both `protect` helpers
used.

`protect` swallows the finalizer's error, so its cleanup cannot raise and it
becomes a plain `defer`. `protect2` deliberately lets the finalizer's error
win, and neither rewrite the lint suggests fits: `defer` may not call a raising
function (error 4174), and `errdefer` is still only a reserved word on the
stable toolchain. It instead captures the outcome as a `Result`, runs the
finalizer on the single shared path, and re-raises afterwards -- the catch arm
no longer cleans up or re-raises.

Behavior is unchanged: "protect & finally raise error" still reports the work
error and "protect2 & finally raise error" still reports the finalizer error.
