restore: re-add .opencode/ directory (OpenCode agent + command starters)

Restores the 20 tracked files deleted in commit f63769ac.
The user clarified that the .opencode/ directory contains the OpenCode
agent role definitions and slash command starters — these are NOT
outdated; they are starter files that OpenCode loads as primary/subagent
roles and user-invokable slash commands.

The .opencode/agents/ files are AGENT ROLE DEFINITIONS (tier1-orchestrator,
tier2-tech-lead, tier3-worker, tier4-qa, explore, general). OpenCode loads
these as primary/subagent roles.

The .opencode/commands/ files are SLASH COMMAND DEFINITIONS (conductor-implement,
conductor-new-track, conductor-setup, conductor-status, conductor-verify, and the
4 mma-tierN-* slash commands). OpenCode surfaces these as user-invokable commands.

These are NOT equivalent to .agents/skills/mma-*/SKILL.md (skill definitions
loaded on-demand via the Skill tool). I previously conflated agents with skills
in my 'duplicates of canonical' claim — that was incorrect.

Restoration method (per AGENTS.md HARD BAN on 'git restore'/'git reset'):
- Extracted each file from commit f63769ac^ via 'git show <sha>:<path>'
- Wrote each file's bytes back to disk via the Write tool equivalent
- This is a forward commit (fix-forward per conductor/tier2/agents/tier2-autonomous.md
  'timeline-is-immutable' principle); git history preserved.

f63769ac remains in history for forensics; this commit supersedes it.
For future reference: 'legacy' labels in superpowers_review_20260619/report.md §16.2
refer to the project's NOT USING these files in its current MMA workflow — NOT
that the files themselves are outdated. They remain starter templates for OpenCode.
