v1.12.0 - Token-Efficient CLI & Mandatory Multi-Agent

Token Efficiency (CLAUDE_TOKEN_EFFICIENCY=1, default enabled)

Two-layer approach to minimize context token consumption:

1. Behavioral guidance (system-prompts/token_efficient_cli.md): Injected via SessionStart hook with mandatory MUST/MUST NOT rules for compact CLI flags (git -sb, ruff --output-format concise --quiet, pytest -q --tb=short, etc). Rules added to all 8 agent definitions and orchestrator template.

2. Output compression (hooks/compact_run.py): PreToolUse hook rewrites matching Bash commands through compact_run.py. Supports git (push/pull/commit/fetch/add/merge/rebase/stash), pytest, cargo test, npm/pnpm/yarn/bun test, npx (vitest/jest/mocha/playwright), go test, make test/check, docker/kubectl logs.

Mandatory Multi-Agent Execution

• Plan mode defaults to team mode when CLAUDE_CODE_EXPERIMENTAL_AGENT_TEAMS=1
• Minimum 2 subtasks per plan (single-subtask plans prohibited)
• Execution section with teammate/agent table in plan output format
• 3 reinforcement points in workflow_orchestrator.md

Test Suite (196 tests)

File	Tests	Coverage
test_compact_run.py	100	All output compression handlers
test_token_rewrite_hook.py	~50	Command matching, metachar, env gating
test_inject_token_efficiency.py	~36	Injection hook, JSON output
test_integration.py	10	End-to-end subprocess

CI enabled with ruff lint + pytest.

Other Changes

• Statusline reorganized: row 1 static info, row 2 dynamic metrics
• Removed alwaysThinkingEnabled from settings
• Windows .exe command normalization
• Configurable subprocess timeout (COMPACT_RUN_TIMEOUT, default 120s)
