fix: properly handle SKILL.md paths in extension update rollback and tests

Fix extension update rollback using _compute_output_name() for SKILL.md
agents (converts dots to hyphens in skill directory names). Previously
the backup and cleanup code constructed paths with raw command names
(e.g. speckit.test-ext.hello/SKILL.md) instead of the correct computed
names (speckit-test-ext-hello/SKILL.md).

Test fixes for claude skills migration:
- Update claude tests to use .claude/skills paths and SKILL.md layout
- Use qwen (not claude) for skills-guard tests since claude's agent dir
  IS the skills dir — creating it triggers command registration
- Fix test_extension_command_registered_when_extension_present to check
  skills path format

1086 tests pass, 0 failures, ruff clean.
