Created during a Zulip thread to change the simpa tactic

This PR wraps each affected declaration with set_option backward.simpa.using.reducibleClose false in to restore the old behavior.

Could you possibly add a description for this PR? I realise it still may be WIP, given the CI is failing, but it would help me to understand what its intent is.

…appers with `simpa!`

The lean4 PR now removes the `backward.simpa.using.reducibleClose` option;
the permissive default-transparency close is opt-in via `simpa!` instead.

Bumps lean-toolchain to pr-release-13636-11336d3.

…lose

Tracks the lean4 PR's switch from prefix-`!` to a `using!` clause: only the
final close-step transparency is changed, leaving `!` available for its
existing auto-unfold meaning.
