chore(release): v1.0.15 (#575)

fix: address coderabbit review comments on role-config docs

- Update `allow_edit` field description to reflect conditional default:
  `true` when table perm is `edit`, `false` for `read_only` or explicit restriction
- Move `record_operations.delete` out of "默认关闭项" into new "默认开启项（条件性）"
  section to accurately reflect it is default-included when `perm = edit`
- Add `view_rule.allow_edit` to "默认开启项（条件性）" section with same logic

+**Dry-run E2E (required for every shortcut change)**
+- Validates request structure without calling real APIs
+- Place in `tests/cli_e2e/dryrun/` or the corresponding domain directory
+- Set env vars `LARKSUITE_CLI_APP_ID`/`APP_SECRET`/`BRAND`, use `--dry-run`, assert method/URL/params
+- No secrets needed — runs on fork PRs
+- Explore correct params with `lark-cli <domain> --help` and `lark-cli schema` first
+
+**Live E2E (required for new flows or behavior changes)**
+- Validates real API round-trips
+- Place in `tests/cli_e2e/<domain>/`
+- Must be self-contained: create -> use -> cleanup
+- Needs bot credentials (CI secrets, skipped on fork PRs)
