claude_storage 1.0.0

# behavior

Invalidation tests for Claude Code session behaviors. Each file covers exactly one behavior
from `docs/claude_code/001_session_behaviors.md`. Tests inspect real `~/.claude/` storage to verify Claude
Code's actual output — if Claude Code changes behavior, the tests go RED.

## Responsibility Table

| `b10_entry_threading.rs` | B10 — entries linked via `parentUuid` |
| `b11_auto_continue.rs` | B11 — `CLAUDE_CODE_AUTO_CONTINUE` env var |
| `b12_agent_session_id_is_parent.rs` | B12 — agent `sessionId` equals parent UUID |
| `b13_subagent_directory_structure.rs` | B13 — `{uuid}/subagents/` hierarchy |
| `b14_agent_meta_json.rs` | B14 — `.meta.json` sidecars with `agentType` |
