When `gh aw add ./my-workflow.md` is run with a local workflow that has
`skills:` entries using local path references (e.g. `.github/skills/my-skill`
instead of the required `owner/repo/path@sha` form), the add command now
automatically rewrites those entries to fully-qualified remote specs before
writing the workflow to `.github/workflows/`.
The rewriting logic:
- Only runs for local workflow sources (sourceInfo.IsLocal)
- Detects local refs as any skill spec without an `@` separator
- Leaves GitHub Actions expressions (${{ ... }}) and already-qualified refs unchanged
- Normalises `./` prefixes and builds `owner/repo/path@sha` using the
  current repository slug and HEAD commit SHA
- Handles both string form (`- .github/skills/my-skill`) and object form
  (`- skill: .github/skills/my-skill`) YAML entries
Changes:
- pkg/cli/add_skill_rewrite.go: new file with detection, rewriting logic,
  and helper functions
- pkg/cli/add_command.go: wire applyLocalSkillRefRewriting into
  processWorkflowContentModifications
- pkg/cli/add_skill_rewrite_test.go: comprehensive unit tests
