@samuelburnham
bench: Drop the formal-conjectures compile benchmark
3b45554
formal-conjectures is a corpus of conjectures, not of proofs, so
compiling it measures the compiler against statements nobody has proved.
That is not what the compile benchmarks are for.
CompileFC existed only to build it: a package whose sole dependency was
formal-conjectures, held at Lean v4.27.0 because the upstream corpus
targets that release. That stale pin was the one thing the nightly
lean-update sweep kept finding to move (#608). Its FC matrix entry in the
benchmark workflow has been commented out since it fell behind, so
nothing in CI loses a job here.
With the pin gone, `. Benchmarks/**` sweeps a tree whose packages all
track the current toolchain, so lean-update needs no steering around it.
