fixup! feat(divan): run each benchmark in its own process

feat(divan): run each benchmark in its own process Adding or changing one benchmark can change the measurement of the benchmarks that run after it in the same process, because they inherit its heap and allocator state. With CODSPEED_PROCESS_ISOLATION set, divan_compat re-executes the bench binary once per benchmark. The parent keeps CLI filtering and URI generation, and passes the entry index (and the arg index for args benches) through __CODSPEED_DIVAN_BENCH_ID. The child looks up only that entry and runs it, so it allocates nothing that depends on the other benchmarks. Each child calls the instrument hooks with its own PID and gets its own callgrind dump. This relies on the runner's existing --trace-children=yes; cargo-codspeed and the runner need no changes. Analysis mode only; walltime (divan_fork) is not covered yet.

chore(deps): upgrade itertools to v0.15 Bump the workspace `itertools` dependency from 0.14.0 to 0.15.0, used by cargo-codspeed and codspeed-divan-compat-macros. Neither crate uses the APIs changed in 0.15 (`Position`, `all_equal_value`), so no code change is needed. itertools 0.15 keeps an MSRV of 1.63, below our 1.85. The vendored criterion fork still pins itertools 0.10, unchanged here. Closes #192 Co-Authored-By: Arthur Pastel <15641577+art049@users.noreply.github.com> Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
