refactor(cli): complete ACBRA compatibility facade

[Maximooch]

What changed

• extracts agent, config/permissions, skills/MCP, project/task, coordination, and diagnostic Typer registration into focused binders
• keeps compatibility exports and provider-free command-group help contracts
• reduces penguin/cli/cli.py from 5,213 lines to 1,045 lines
• records ACBRA verification evidence
• adds a provenance-aware configuration/capability follow-up plan informed by features.md

Why

The entry point still owned thousands of lines of unrelated command registration and captured mutable globals, making help, monkeypatching, and future config work fragile.

Impact

cli.py is now a composition/compatibility facade. Commands retain their public names, options, and legacy callable exports while their registration lives with the relevant surface.

Validation

• CLI-focused suite: 134 passed
• repository tests/: 2,375 passed, 3 skipped, 113 deselected; four unrelated failures documented
• misc/tests: blocked by stale penguin.penguin.tools.core.old_memory_search import
• compileall passed; purpose-built extracted services pass Ruff
• wheel and sdist built successfully
• isolated installed-wheel smoke passed for root, config, project, and agent help

Stack: #82 → startup PR → runtime PR → this PR.

CI note

The two Link-provider jobs and Python 3.9 goal job are inherited unchanged from base PR #82. Python 3.12 goal, TUI, docs, and deployment checks pass.
