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

fix: base role view & record default perm on edit(#530 )
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 Co-authored-by: Claude Sonnet 4.6 (1M context) <noreply@anthropic.com>

+- 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
