fix: zsh glob compatibility across all skill templates (v0.12.8.1) (#559)

* fix: replace zsh-incompatible raw globs with find-based alternatives and setopt guards

Zsh's NOMATCH option (on by default) causes raw globs like `*.yaml` and
`*deploy*` to throw errors when no files match, instead of silently expanding
to nothing as bash does. The preamble resolver already handled this correctly
with find, but 38 glob instances across 13 templates and 2 resolvers still
used raw shell globs.

Two fix approaches based on complexity:
- find-based replacement for cat/for/ls-with-pipes patterns (.github/workflows/)
- setopt +o nomatch guard for simple ls -t patterns (~/.gstack/, ~/.claude/)

* chore: bump version and changelog (v0.12.8.1)

* test: add zsh glob safety test + fix 2 missed resolver globs

Adds a test that scans all generated SKILL.md bash blocks for raw glob
patterns and verifies they have either a find-based replacement or a
setopt +o nomatch guard. The test immediately caught 2 unguarded blocks
in review.ts (design doc re-check and plan file discovery).

Also syncs package.json version to 0.12.8.1.
