dan ead1b97500 chore: deprecate per-repo skill loading (use-skills.sh)
Skills are now deployed globally via Home Manager. Per-repo loading
added 1-2s delay on every cd and was 100% redundant with global
deployment.

Script retained for backward compatibility but will be removed.

# DEPRECATED: Per-repo skill loading is no longer recommended.
#
# Skills are now deployed globally via Home Manager (dotfiles/home/claude.nix).
# This eliminates the 1-2 second delay on every `cd` caused by nix build calls.
#
# If you have a .skills file or source this script in .envrc, you can safely
# remove those lines. All skills are available globally at ~/.claude/skills/,
# ~/.codex/skills/, etc.
#
# This script remains for backward compatibility but will be removed in a
# future update. See: https://github.com/dan/skills/issues/y7h4

# use_skills worklog web-search
#
# Or with manifest file:
# source ~/proj/skills/bin/use-skills.sh
# load_skills_from_manifest

# Default to per-repo Codex skills unless overridden by the caller.
