/**
 * Regression for #3689 — /msd-resume-work silently drops
 * `.planning/.continue-here*.md` checkpoints under zsh's default NOMATCH.
 *
 * Root cause: the `check_incomplete_work` step in
 * `msd-core/workflows/resume-project.md` used a chained `ls` with six
 * bare-glob arguments. Under zsh's default `NOMATCH` setopt the first
 * non-matching glob aborts the entire command during word-expansion — every
 * pattern after that point is never evaluated, including the one that holds
 * valid pause checkpoints (`.planning/.continue-here*.md`). `2>/dev/null ||
 * true` only suppresses ls's own stderr / exit code; it has no effect on the
 * shell's pre-exec abort.
 *
 * Fix: replace the chained `ls` with two `find` calls. `find` does not use
 * shell glob expansion, and `find <missing-dir> -maxdepth N -name PATTERN
 * -print 2>/dev/null` tolerates absent directories on both bash and zsh.
 *
 * This test covers:
 *   1. zsh under `-o nomatch`: checkpoint at `.planning/.continue-here-*.md`
 *      is listed even when `.planning/spikes`, `.planning/sketches`,
 *      `.planning/deliberations` are absent (the common new-project layout).
 *   2. bash default: same behavior.
 *   3. zsh `-o nomatch` with no `.continue-here` files anywhere: exits 0,
 *      no output, no error.
 *   4. Text invariant: resume-project.md no longer carries the brittle
 *      chained-ls pattern.
