Bump all manifests to 6.1.0 and add RELEASE-NOTES for v6.1.0:
- Compress the using-superpowers bootstrap and prune per-harness
tool-mapping references (lower per-session token cost).
- Add a Codex marketplace manifest so the plugin installs from Codex;
drop the Codex SessionStart hook.
- Remove Gemini CLI support (Google EOLed the Gemini CLI 2026-06-18).
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)
