Bump all plugin manifests to 6.0.3. This release moves subagent-driven-
development's scratch artifacts (task briefs, implementer reports, review
diffs, progress ledger) from .git/sdd/ — which Claude Code denies agent
writes to — into a self-ignoring working-tree .superpowers/sdd/ dir, and
bumps the brainstorm-server test harness's ws dependency to clear two
dependabot alerts. See RELEASE-NOTES.md.
- Brainstorm companion reads version from .codex-plugin/plugin.json when package.json is absent (PRI-2240)
- sync-to-codex script excludes .gitmodules and .pre-commit-config.yaml (PRI-1168)
