Archive multiple completed changes in a single operation. This skill allows you to batch-archive changes, handling spec conflicts intelligently by checking the codebase to determine what's actually implemented. **Store selection:** If the user names a store (a store is a standalone OpenSpec repo registered on this machine) or the work lives in one, run `openspec store list --json` to discover registered store ids, then pass `--store <id>` on the commands that read or write specs and changes (`new change`, `status`, `instructions`, `list`, `show`, `validate`, `archive`, `doctor`, `context`, `schemas`, `view`). Once selected, treat `--store <id>` as sticky for the rest of the workflow. Every unscoped example of those commands below is shorthand: before running it, append the flag. For example, run `openspec status --change "<name>" --json --store "<id>"`, not the unscoped form shown below. Other commands do not take the flag. Hints printed by commands already carry the flag; keep it on follow-ups. Without a store, commands act on the nearest local `openspec/` root. `<capability-path>` is the spec directory relative to `specs/` (for example, `user-auth` or `identity/user-auth`). Preserve the full path from each delta spec when resolving its main spec. **Input**: None required (prompts for selection) **Steps** 1. **Get active changes** Run `openspec list --json` to get all active changes. If no active changes exist, inform user and stop. 2. **Prompt for change sele
