Add to config (default: 40, range: 20-500).
Controls how many characters of tool hints are shown in progress updates
(e.g. '$ cd …/project && npm test').
Set to 120+ to see full commands instead of truncated hints:
```json
{
"agents": {
"defaults": {
"toolHintMaxLength": 120
}
}
}
```
- Thread max_length through format_tool_hints → _fmt_known/_fmt_mcp/_fmt_fallback
- Make path abbreviation in _abbreviate_command proportional to max_length
- Add TestToolHintMaxLength test class with 5 tests
- All 41 existing tests pass
Preserve path folding for quoted exec command paths with spaces so hint previews do not fall back to mid-path truncation. Add regression coverage for quoted Unix and Windows path cases.

1. exec tool hints previously used val[:40] blind character truncation,
cutting paths mid-segment. Now detects file paths via regex and
abbreviates them with abbreviate_path. Supports Windows, Unix
absolute, and ~/ home paths.
2. Deduplication now compares fully formatted hint strings instead of
tool names alone. Fixes ls /Desktop and ls /Downloads being
incorrectly merged as "ls /Desktop × 2".

- Move _tool_hint implementation from loop.py to nanobot/utils/tool_hints.py
- Keep thin delegation in AgentLoop._tool_hint for backward compat
- Update test imports to test format_tool_hints directly
