Bump edition 2021 -> 2024. rust-version stays at 1.91, already well above
the 1.85 floor the edition needs; docs/guide/resources/troubleshooting.md
still claimed 1.70+, which is where a failed `cargo install --git` lands.
Four things the edition forces:
- std::env::{set_var,remove_var} are unsafe in 2024 with no safe std
replacement. Rather than wrap the test call sites in unsafe -- which the
crate denies and .semgrep.yml flags -- route them through temp-env, a
dev-only dependency whose closure API is safe and which restores the
previous value even when the body panics. The hand-rolled CLAUDE_DIR_LOCK
and PI_DIR_LOCK guards existed only to serialise those mutations and are
now redundant; CWD_LOCK and TEST_ENV_LOCK stay, they order more than the
env var itself.
- unsafe_op_in_unsafe_fn is on by default, so the libc calls in the proxy
signal handler and in stream.rs's relay handler need explicit unsafe
blocks, scoped to the libc calls themselves.
- `gen` is a reserved keyword, so the closure by that name in diff_cmd.rs
becomes make_lines.
- Tightened tail-expression temporary scopes let clippy prove the binding in
setup_test_env is inlinable, so let_and_return now fires there.
if_let_rescope changes when the scrutinee temporary drops in an if let/else.
The two sites in show_claude_config take cargo fix --edition's match rewrite,
which keeps the 2021 drop timing.
rustfmt.toml is kept rather than dropped: cargo fmt passes --edition from
Cargo.toml, but a bare rustfmt invocation has no crate context and falls
back to edition 2015, which cannot parse the let-chains the next commit
introduces. Pinning it there keeps format-on-save and pre-commit hooks in
agreement with CI.
clippy::collapsible_if is allowed crate-wide for now; the follow-up commit
adopts let-chains and removes the allow.
