* chore: fix some defeq abuse in theorem statements around the `Id` monad (#25098)

Follows on from leanprover/lean4#7352.

This also deprecates:
* `id.mk`, which looks like a porting error
* `Free(Add)(Magma|Semigroup).mul_map_seq`, which is a garbage lemma that both is not meaningfully about the free objects and has defeq abuse everywhere.

* fix(Shake): fix import syntax

@Kha this is deliberately using this approach because syntax quotations
are also not robust but for a different reason: they fail to parse the
new versions of the syntax (and do so at run time). And using all the
optional doohickeys will not be future proof. The current setup is
explicitly meant to ping me when there is a syntax change so I can
evaluate the right way to handle it. In this case we want all the
module options to be ignored (treated the same as a regular import
for the purpose of dependency tracking), we don't want to fail.

* fix(Shake): fix import syntax

@Kha this is deliberately using this approach because syntax quotations
are also not robust but for a different reason: they fail to parse the
new versions of the syntax (and do so at run time). And using all the
optional doohickeys will not be future proof. The current setup is
explicitly meant to ping me when there is a syntax change so I can
evaluate the right way to handle it. In this case we want all the
module options to be ignored (treated the same as a regular import
for the purpose of dependency tracking), we don't want to fail.

* feat: add algebra shims for Grind.Nat/IntModule (leanprover-community#26133)

This PR adds shims so `grind` will understand Mathlib's `AddCommMonoid` and `AddCommGroup`. (Subsequent shims will connect up the order structures for modules and rings.)

* fix

* Update lean-toolchain for leanprover/lean4#8699

* fix: correct memoFix's use of unsafe code

* fix: adjust noncomputable annotations for new compiler

* fix: replace use of `open private _ in` with `open private _ from`

The implementation of `open private _ from` relies on specific
internals of the old compiler and will no longer work.

* remove mul_hmul

* chore: adjust one maxHeartbeats for the new compiler

* linter

* feat: generalize grind algebra shims (leanprover-community#26131)

This PR extends the shims converting from Mathlib to `Lean.Grind` typeclasses, now that `grind` knows about (non-commutative)-(semi)-rings.
