/**
 * This command determines if there were any changes since the last release in a
 * cross-platform compatible way. It is used as a condition for both the `bump`
 * and the `release` tasks: it exits 0 (proceed) when the most recent commit is
 * not a release commit, and non-zero (skip) when the most recent commit is a
 * `chore(release):` commit.
 *
 * Explanation:
 *  - `git log --oneline -1`          the most recent commit, one line
 *  - `| grep -v "chore(release):"`   pass the line through only if it is NOT a release commit
 *  - `> /dev/null`                   discard grep's output; only its exit code matters
 *
 * grep exits 0 when it prints at least one non-matching line (a normal commit,
 * so proceed) and 1 when every line matches (a release commit, so skip).
 *
 * IMPORTANT: do NOT reintroduce `grep -q` here (i.e. do not "optimize" this back
 * to `grep -qv`). `grep -q` exits as soon as it has an answer and closes the read
 * end of the pipe. When this condition runs through projen's built-in (dax)
 * shell, that early close races with `git log` still writing to the pipe, and dax
 * surfaces the failed write as a spurious non-zero exit ("stdin pipe broken.
 * Invalid state: WritableStream is closed"). The task runtime cannot distinguish
 * that from a legitimate skip (dax reports it as a plain non-zero code under
 * `.noThrow()`, not as an error), so the bump/release task is silently skipped: a
 * release is missed, or a dependent publishes a broken `^0.0.0` version range.
 * Plain `grep -v ... > /dev/null` reads to EOF instead of short-circuiting, so it
 * never closes the pipe while the writer is active and the race cannot occur. The
 * exit semantics are identical to the previous `grep -qv`.
