zsh errors on globs that match nothing instead of returning the literal
pattern (bash's default), and `2>/dev/null` does not suppress the error
because it comes from the shell's glob expansion before `ls` even runs.
Under Codex (which executes the SKILL.md bash via zsh), STEP 0 and the
Step 1 / comparison-mode resolvers emitted noisy "no matches found"
errors on machines without a Claude plugin cache populated.
Replaces all three `ls -d $HOME/.claude/plugins/cache/last30days-skill/last30days/*/`
invocations with `find ... -mindepth 1 -maxdepth 1 -type d 2>/dev/null`.
find is POSIX-portable, errors silently when the base dir doesn't exist,
and never triggers shell glob errors. `sort -V | tail -1` precedence
preserved (verified: picks 3.10.0 over 3.2.1 over 3.1.0). Trailing-slash
strip removed because find doesn't append slashes.
Observed in Codex session running /last30days against PR #400 with the
Claude plugin cache deleted - bash output was:
zsh:1: no matches found: /Users/.../last30days/*/
After fix: clean empty output, exit 0, STEP 0 correctly treats it as
"no cache present, do not hop", resolver falls through to per-harness
skill dirs as designed.
