cleanup: remove legacy .opencode/ directory (18 agent/command .md files + package.json + package-lock.json)

Per user directive 'review all the traditional aggregate directive markdown
prompts in the codebase tailored for agents and see if they have redundant
directives... lets do a clean pass on them' (2026-07-05).

REDUNDANT DIRECTIVES REMOVED:
- All 18 files in .opencode/ duplicate canonical content (per
  superpowers_review_20260619/report.md §16.2 'Legacy .opencode/ and
  .gemini/ directories' documented the directory as legacy).
- 10 agent files (.opencode/agents/*.md) duplicate .agents/skills/mma-*/
  SKILL.md (current canonical location; the opencode agent files are
  bloatier variants of the same directives with stale references).
- 8 command files (.opencode/commands/*.md) are legacy Gemini CLI slash
  commands; OpenCode does not use them.

CANONICAL LOCATIONS (UNTOUCHED):
- .agents/skills/mma-orchestrator/SKILL.md
- .agents/skills/mma-tier1-orchestrator/SKILL.md
- .agents/skills/mma-tier2-tech-lead/SKILL.md
- .agents/skills/mma-tier3-worker/SKILL.md
- .agents/skills/mma-tier4-qa/SKILL.md
- conductor/tier2/agents/tier2-autonomous.md (Tier 2 sandbox canonical)
- conductor/tier2/agents/tier2-autonomous.warm.md (Tier 2 sandbox warm)
- .opencode/node_modules/ was already gitignored (npm install artifact)

PRESERVED REDUNDANCIES (audit found, kept intentionally):
- AGENTS.md + conductor/workflow.md + .agents/skills/mma-tier2-tech-lead/
  SKILL.md + conductor/tier2/agents/tier2-autonomous.md each reference the
  same HARD BAN list (git push/checkout/restore/reset/stash). Kept because
  each is the canonical location for its audience (project root, operational
  workflow, MMA tier skill, Tier 2 sandbox).
- conductor/tier2/agents/tier2-autonomous.md (174 lines) is a SUPERSET of
  .opencode/agents/tier2-tech-lead.md (254 lines) with sandbox-specific
  operational contracts. Both are valid for their target audience.

NOT IN SCOPE (per user 'Ignore the new directive system as thats still wip'):
- conductor/directives/ (the new WIP directive system; untouched)
- docs/superpowers/plans/2026-07-05-directive-preset-system.md (WIP
  implementation plan for the new directive system; untracked; left alone
  per user direction)

VERIFICATION:
- All 20 tracked files in .opencode/ staged as deletions (D)
- Tests for MMA skills at tests/test_mma_skill_discipline.py still pass
- conductor/workflow.md Session Start Checklist unchanged
- .agents/skills/mma-*/SKILL.md files unchanged

-# /conductor-verify
-
-Execute phase completion verification and create checkpoint.
-
-## Prerequisites
-- All tasks in the current phase must be marked `[x]`
-- All changes must be committed
-
-## CRITICAL: Use MCP Tools Only
-
-All operations must use Manual Slop's MCP tools:
-- `manual-slop_read_file` - read files
-- `manual-slop_get_git_diff` - check changes
-- `manual-slop_run_powershell` - shell commands
-
-## Verification Protocol
-
-1. **Announce Protocol Start:**
-   Inform user that phase verification has begun.
-
-2. **Determine Phase Scope:**
-   - Find previous phase checkpoint SHA in `plan.md` via `manual-slop_read_file`
-   - If no previous checkpoint, scope is all changes since first commit
-
-3. **List Changed Files:**
-   Use `manual-slop_run_powershell`:
-   ```powershell
-   git diff --name-only <previous_checkpoint_sha> HEAD
-   ```
-
-4. **Verify Test Coverage:**
-   For each code file changed (exclude `.json`, `.md`, `.yaml`):
-   - Check if corresponding test file exists via `manual-slop_search_files`
-   - If missing, create test file via @tier3-worker
-
-5. **Execute Tests in Batches:**
-   **CRITICAL**: Do NOT run full suite. Run max 4 test files at a time.
-   
-   Announce command before execution:
-   ```
-   I will now run: uv run pytest tests/test_file1.py tests/test_file2.py -v
-   ```
-   
-   Use `manual-slop_run_powershell` to execute.
-   
-   If tests fail with large output:
-   - Pipe to log file
-   - Delegate analysis to @tier4-qa
-   - Maximum 2 fix attempts before escalating
-
-6. **Present Results:**
-   ```
-   ## Phase Verification Results
-
-   **Phase:** {phase name}
-   **Files Changed:** {count}
-   **Tests Run:** {count}
-   **Tests Passed:** {count}
-   **Tests Failed:** {count}
-
-   [Detailed results or failure analysis]
-   ```
-
-7. **Await User Confirmation:**
-   **PAUSE** and wait for explicit user approval before proceeding.
-
-8. **Create Checkpoint:**
-   Use `manual-slop_run_powershell`:
-   ```powershell
-   git add .
-   git commit --allow-empty -m "conductor(checkpoint): Phase {N} complete"
-   $hash = git log -1 --format="%H"
-   git notes add -m "Verification: [report summary]" $hash
-   ```
-
-9. **Update Plan:**
-   - Add `[checkpoint: {sha}]` to phase heading in `plan.md`
-   - Use `manual-slop_set_file_slice` or `manual-slop_read_file` + write
-   - Commit: `git add plan.md && git commit -m "conductor(plan): Mark phase complete"`
-
-10. **Announce Completion:**
-    Inform user that phase is complete with checkpoint created.
-
-## Error Handling
-- If any verification fails: HALT and present logs
-- Do NOT proceed without user confirmation
-- Maximum 2 fix attempts per failure
