chore: regenerate Cargo.lock after 1027's unused-dep cleanup

cargo-machete dropped eventsource-stream, indexmap, serde_yaml, and
strip-ansi-escapes from server/Cargo.toml in 1027 (4fad2838), but the
Cargo.lock didn't regenerate as part of that merge. The lockfile was
sitting dirty on master, blocking subsequent cherry-picks (1026 hit
'Your local changes to the following files would be overwritten by
merge: Cargo.lock').

This commit is the missing lockfile catch-up — drops the four crates
(and their transitives nom + minimal-lexical) from the lock.
