fix(codex): invoke Windows hook command through PowerShell

Prompt: Jesse questioned whether the PR should remove the hooks config from the Codex plugin manifest.

Runtime investigation showed Codex accepts a committed plugin manifest with hooks and installs the plugin successfully. Removing the field changes behavior: Codex falls back to the default hooks/hooks.json, which uses the non-Codex session-start hook and CLAUDE_PLUGIN_ROOT path, instead of hooks/hooks-codex.json and the session-start-codex script.

Changes: restore .codex-plugin/plugin.json hooks to ./hooks/hooks-codex.json and update the Codex marketplace manifest test to require that Codex-specific hook pointer instead of rejecting hooks.

Validation: bash tests/codex/test-marketplace-manifest.sh; scripts/lint-shell.sh tests/codex/test-marketplace-manifest.sh; bash tests/codex-plugin-sync/test-sync-to-codex-plugin.sh; bash tests/kimi/test-plugin-manifest.sh; bash tests/shell-lint/test-lint-shell.sh.

 # Superpowers Release Notes
 
+## v6.0.3 (2026-06-18)
+
+### Subagent-Driven Development
+
+- **SDD scratch files moved out of `.git/`.** Claude Code treats `.git/` as a protected path and denies agent writes there, so an implementer subagent writing its report into `.git/sdd/` got blocked mid-run. Task briefs, implementer reports, review diffs, and the progress ledger now live in a self-ignoring `.superpowers/sdd/` directory in the working tree — kept out of `git status` and out of commits, and resolved per worktree by a shared `sdd-workspace` helper. One caveat: because the workspace is git-ignored working-tree scratch, `git clean -fdx` will delete the progress ledger; recover from `git log` if that happens. (#1780)
