Daniel Griesser a68d57cfa6 fix(scripts): harden build-skill-tree.sh for bash 3.2 on macOS ...

Use ${ARRAY[@]+"${ARRAY[@]}"} pattern for all array expansions that
could be empty (category arrays, errors array, function parameters).
Bash 3.2 with set -u treats "${EMPTY[@]}" as an unbound variable error,
while bash 4+ handles it gracefully. The +"..." syntax expands to nothing
when the array is unset/empty, avoiding the crash.

Also fix AGENTS.md claiming CI only runs on skills/** changes — the
validate-skill-tree job runs on all PRs (it's fast enough not to need
path filtering).
