Polish Agent defaults and ignore crate-local agent artifacts

Move the default Agent artifact store out of rust/crates/tools so repeated Agent runs stop generating noisy crate-local files, normalize explicit Agent names through the existing slug path, and ignore any crate-local .clawd-agents residue defensively. Keep the slice limited to the tools crate and preserve the existing manifest-writing behavior.

Constraint: Must not touch unrelated dirty api files in this worktree
Constraint: Keep the change limited to rust/crates/tools
Rejected: Add a broader agent runtime or execution model | outside the final cleanup slice
Confidence: high
Scope-risk: narrow
Reversibility: clean
Directive: Keep Agent persistence defaults outside package directories so generated artifacts do not pollute crate working trees
Tested: cargo test -p tools
Not-tested: concurrent multi-process Agent writes to the default fallback store

-> **Clean-room Claude Code harness - mirrored for architectural study**
-
----
-
-## ⚠️ IMPORTANT: Reference Only
-
-This repository is a **mirror** of [instructkr/claw-code](https://github.com/instructkr/claw-code) for:
-- ✅ Studying agent harness engineering patterns
-- ✅ Comparing tool system architectures  
-- ✅ Learning clean-room implementation approaches
-
-**Do NOT copy code directly.** Study patterns, then implement independently.

-## 🏗️ Architecture
-
-### Python (`src/`)
-```
-runtime.py          → Agent runtime with routing
-├── tools.py        → Tool harness (Bash, File, MCP)
-├── commands.py     → Command system
-├── query_engine.py → LLM orchestration
-├── permissions.py  → Tool permission contexts
-└── bootstrap/      → Initialization
-```
-
-### Rust (`rust/crates/`)
-```
-api/                → Anthropic-compatible client
-tools/              → Tool system
-compat-harness/     → Compatibility layer
-rusty-claude-cli/   → CLI interface
-```
-

-
-## 🔗 Key Patterns
-
-### 1. Tool Permission Context
-```python
-@dataclass
-class ToolPermissionContext:
-    deny_tools: set[str]
-    deny_prefixes: tuple[str, ...]
-    
-    def blocks(self, tool_name: str) -> bool:
-        return tool_name in self.deny_tools or \
-               any(tool_name.startswith(p) for p in self.deny_prefixes)
-```
-
-### 2. Execution Registry
-- Routes prompts to commands/tools
-- Filters by permission context
-- Handles execution lifecycle
-
-### 3. Session Persistence
-- JSON-based session store
-- Turn-by-turn history
-- Context preservation
