fix(adapters): escape YAML frontmatter values consistently across all command adapters

+
+Generated tool command files now carry valid YAML frontmatter for every supported tool. Command names ship as `OPSX: Explore`, and the unquoted `name: OPSX: Explore` that adapters emitted is not parseable YAML — strict parsers rejected the whole file, so the command failed to load. Several adapters also re-implemented their own escaping, and a few interpolated descriptions in raw.
+
+Escaping now lives in one place (`escapeYamlValue` / `formatTagsArray`) and every adapter uses it. String frontmatter values are always double-quoted, which also keeps values like `true`, `null` and `123` from round-tripping as booleans, nulls and numbers. Non-string fields such as `allowed-tools` and `invokable` are unchanged. Expect the first `openspec update` after upgrading to rewrite the frontmatter lines of your generated command files.
+
+Archive workflow guidance also gets two corrections: bulk archive now carries its per-delta include/exclude decisions into execution, so a delta whose implementation was not found is reported as `sync skipped` instead of being synced anyway, and both archive workflows verify the main specs before moving the change directory.

 8. **Execute archive for each confirmed change**
 
+   Before processing, carry the recorded decisions from step 5 (after any step 7 re-derivation) into two per-delta sets:
+   - `includedDeltas`: all non-conflicting delta specs from confirmed changes plus conflict deltas selected for sync
+   - `excludedDeltas`: conflict deltas from confirmed changes excluded because their implementation is missing
+   - A single change can have both included and excluded delta specs. Keep the decision per delta; do not collapse it into a per-change sync flag.
+
    Process changes in the determined order (respecting conflict resolution):
 
-   a. **Sync specs** if delta specs exist:
-      - Use the openspec-sync-specs approach (agent-driven intelligent merge)
-      - For conflicts, apply in resolved order
+   a. **Sync included delta specs**:
+      - Run the `openspec-sync-specs` workflow inline (agent-driven intelligent merge) only for changes with entries in `includedDeltas`, passing only the included delta paths and explicitly instructing it to ignore that change's `excludedDeltas`. Wait for it to finish.
+      - For conflicts, apply in resolved order.
       - Pass that change's fetched specs-rule snapshot into inline sync; inline
         sync must reuse it without fetching instructions again
       - Apply artifact rules only to main specs produced by that change. They do
         not change conflict resolution, archive behavior, or CLI contracts, and
         their text is not copied into an output file
-      - Track if sync was done
+      - Do not delegate to a background task — step 8c would move `changeRoot` out from under a sync that is still reading it.
+      - If a change has no included delta specs, do not run the sync workflow for it.
+
+   b. **Verify included delta specs before moving changeRoot**:
+      - Re-run the comparison only for delta specs in `includedDeltas` against main spec at `<planningHome.root>/openspec/specs/<capability>/spec.md` (use the store-aware `planningHome.root` from step 3 status JSON, not a hardcoded repo path).
+      - Verify that main specs are updated:
+        - ADDED requirements present
+        - MODIFIED requirements carrying scenario and description changes named in the delta, with their other scenarios intact
+        - REMOVED requirements gone
+        - RENAMED requirements present under the new name and absent under the old one
+      - Do not verify delta specs in `excludedDeltas`; they are intentionally left unsynced.
+      - If sync failed or any capability does not match verification, report what differs and fail/skip moving that change's `changeRoot` — do not archive that change. `changeRoot` remains intact.
