feat(cya): T01-T07 core console-native MVP slice (CYA-WP-0001)

- T01: Python + Typer/rich + pyproject.toml + full src/ layout + working `cya` CLI entrypoint
- T02: Bounded transparent context collector (top-level only, provenance, ignores) + --explain-context
- T03: Genuine rule-based risk classifier (primary) + mandatory terminal confirmation, no auto-execute
- T04: LLMAdapter Protocol + deterministic FakeLLMAdapter seam (llm-connect boundary, zero bypass)
- T05: Strictly minimal phase-memory no-op ports (loud markers, per operator direction 2026-05-26)
- T06: Orchestrator coordinating the full flow; CLI is thin delegation
- T07: pytest harness + safety-focused tests (risk invariants + collector)

All changes verified by running the installed `cya` binary and `pytest tests/`.

Workplan updated with status. State Hub progress event logged (workstream 0a1233fd...).
