Describe the bug

Context:

MSRV check is currently only done in CI

iceberg-rust/.github/workflows/ci.yml

Lines 164 to 173 in 66ba909

	- name: Generate minimal versions lockfile
	run: |
	cargo generate-lockfile -Z direct-minimal-versions
	- name: Setup MSRV Rust toolchain
	uses: ./.github/actions/setup-builder
	with:
	rust-version: ${{ env.rust_msrv }}
	- name: Check MSRV
	run: |
	cargo +${{ env.rust_msrv }} check --locked --workspace

This would require multiple roundtrips and checking against CI, which is costly.
I propose that we add a new Makefile command to run this MSRV check.

check-msrv:
    cargo generate-lockfile -Z direct-minimal-versions
    cargo check --locked --workspace

We have to ensure the use of the MSRV version from Cargo.toml's rust-version field here somehow...

iceberg-rust/Cargo.toml

Line 39 in 66ba909

rust-version = "1.87"

The check itself, mainly the cargo generate-lockfile command, also generates a new Cargo.lock file which should not be checked in. This can be a potential footgun when upgrading libraries, as we've seen in #1501. Perhaps in the make command, we can also restore any Cargo.lock file changes to prevent footgun.

+1, this improves developer experience. I love everything locally reproducable.
