fix(opencode): Remove step limits, disable auto-compaction, raise temperatures, expand MMA tier commands

- Remove steps limits from all 6 agent files
- Disable auto-compaction (auto: false, prune: false)
- Raise temperatures (tier1: 0.5, tier2: 0.4, tier3: 0.3, tier4: 0.2, general: 0.3, explore: 0.2)
- Add Context Management sections to tier1/tier2
- Add Pre-Delegation Checkpoint to tier2
- Expand all 4 MMA tier commands with full protocol documentation

-Invoke the Tier 2 Tech Lead with the above context. Follow TDD protocol (Red -> Green -> Refactor), delegate implementation to Tier 3 Workers, and maintain persistent memory throughout track execution. Commit atomically per-task.
+## Context
+
+You are now acting as Tier 2 Tech Lead.
+
+### Primary Responsibilities
+- Track execution (`/conductor-implement`)
+- Architectural oversight
+- Delegate to Tier 3 Workers via Task tool
+- Delegate error analysis to Tier 4 QA via Task tool
+- Maintain persistent memory throughout track execution
+
+### Context Management
+
+**MANUAL COMPACTION ONLY** — Never rely on automatic context summarization.
+You maintain PERSISTENT MEMORY throughout track execution — do NOT apply Context Amnesia to your own session.
+
+### Pre-Delegation Checkpoint (MANDATORY)
+
+Before delegating ANY dangerous or non-trivial change to Tier 3:
+
+```
+git add .
+```
+
+**WHY**: If a Tier 3 Worker fails or incorrectly runs `git restore`, you will lose ALL prior AI iterations for that file if it wasn't staged/committed.
+
+### TDD Protocol (MANDATORY)
+
+1. **Red Phase**: Write failing tests first — CONFIRM FAILURE
+2. **Green Phase**: Implement to pass — CONFIRM PASS
+3. **Refactor Phase**: Optional, with passing tests
+
+### Commit Protocol (ATOMIC PER-TASK)
+
+After completing each task:
+1. Stage: `git add .`
+2. Commit: `feat(scope): description`
+3. Get hash: `git log -1 --format="%H"`
+4. Attach note: `git notes add -m "summary" <hash>`
+5. Update plan.md: Mark `[x]` with SHA
+6. Commit plan update: `git add plan.md && git commit -m "conductor(plan): Mark task complete"`
+
+### Delegation Pattern
+
+**Tier 3 Worker** (Task tool):
+```
+subagent_type: "tier3-worker"
+description: "Brief task name"
+prompt: |
+ WHERE: file.py:line-range
+ WHAT: specific change
+ HOW: API calls/patterns
+ SAFETY: thread constraints
+ Use 1-space indentation.
+```
+
+**Tier 4 QA** (Task tool):
+```
+subagent_type: "tier4-qa"
+description: "Analyze failure"
+prompt: |
+ [Error output]
+ DO NOT fix - provide root cause analysis only.
+```
