This PR adds support to the server for the new module setup process by
changing how `lake setup-file` is used.

In the new server setup, `lake setup-file` is invoked with the file name
of the edited module passed as a CLI argument and with the parsed header
passed to standard input in JSON form. Standard input is used to avoid
potentially exceeding the CLI length limits on Windows. Lake will build
the module's imports along with any other dependencies and then return
the module's workspace configuration via JSON (now in the form of
`ModuleSetup`). The server then post-processes this configuration a bit
and returns it back to the Lean language processor.

The server's header is currently only fully respected by Lake for
external modules (files that are not part of any workspace library). For
workspace modules, the saved module header is currently used to build
imports (as has been done since leanprover#7909). A follow-up Lake PR will align
both cases to follow the server's header.

Lean search paths (e.g., `LEAN_PATH`, `LEAN_SRC_PATH`) are no longer
negotiated between the server and Lake. These environment variables are
already configured during sever setup by `lake serve` and do not change
on a per-file basis. Lake can also pre-resolve the `.olean` files of
imports via the `importArts` field of `ModuleSetup`, limiting the
potential utility of communicating `LEAN_PATH`.

@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.

* chore: bump to nightly-2025-06-19

* 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.
