chore(openspec): archive 5 merged changes from PRs #546-550 (#551)

Move the OpenSpec changes for today's 5 shipped fixes from
openspec/changes/ to openspec/changes/archive/2026-05-11-<slug>/
via `openspec archive --skip-specs -y`:

- agent-claude-fix-guardex-dirty-tree-sweep-leak (PR #546)
- agent-claude-submodule-pointer-conflict-resolver (PR #547)
- agent-claude-canonicalize-templates-scripts (PR #548)
- agent-claude-fix-openspec-scaffold-silent-failure (PR #549)
- agent-claude-fix-cleanup-orphan-worktree-prune (PR #550)

All five are merged on origin/main; their active entries were
polluting `openspec list` and the contract requires merged changes
to live under archive/YYYY-MM-DD-<slug>/.

`--skip-specs` was used because the deltas in those changes already
landed via the merged PRs; running the spec-sync step at archive
time would have re-applied them on top of themselves.
