feat(T2267, T2320): Fix commands and add activity mappings

[thjont]

Summary

• T2267 (RoboVac L60): Fix pause, stop, return home, and locate commands using correct protobuf-encoded values
• T2320 (X9 Pro): Add protobuf command support matching T2267 patterns, comprehensive status mappings for station states
• Add activity_mapping for proper Home Assistant vacuum state reporting
• Add status_patterns and error_patterns for handling dynamic protobuf values with embedded timestamps
• Expand error code handling with 770+ error definitions
• Add CLAUDE.md for AI-assisted development guidance

Changes

T2267 (RoboVac L60)

• Fix START_PAUSE command: now uses code 152 with protobuf values (AggN for pause, AggO for resume)
• Fix STOP command: uses code 152 with protobuf value AggM (STOP_TASK method 12)
• Fix RETURN_HOME command: uses code 152 with protobuf value AggG (START_GOHOME method 6)
• Add CLEAN_SPOT to homeassistant_features
• Convert STATUS values from list to dict with human-readable names
• Add comprehensive activity_mapping for VacuumActivity states
• Add status_patterns for matching positioning codes with dynamic timestamps
• Add error_patterns to filter false error states

T2320 (X9 Pro)

• Add protobuf-encoded commands matching T2267 patterns
• Add extensive STATUS values for station states (washing mop, drying mop, emptying dust, etc.)
• Add activity_mapping including station-specific states
• Add status_patterns and error_patterns for dynamic value handling

Core Changes

• base.py: Add STOP command to RobovacCommand enum
• robovac.py: Add pattern matching support for STATUS and ERROR codes
• vacuum.py: Integrate activity mapping and improve state handling
• errors.py: New file with 770+ error code definitions from protobuf reference
• sensor.py: Support model-specific battery DPS codes

🛠 Guidelines to remediate hardcoded secrets

1. Understand the implications of revoking this secret by investigating where it is used in your code.
2. Replace and store your secret safely. Learn here the best practices.
3. Revoke and rotate this secret.
4. If possible, rewrite git history. Rewriting git history is not a trivial act. You might completely break other contributing developers' workflow and you risk accidentally deleting legitimate data.

To avoid such incidents in the future consider

• following these best practices for managing and storing secrets including API keys and other credentials
• install secret detection on pre-commit to catch secret before it leaves your machine and ease remediation.

I think the GitGuardian Security Check is finding a bluetooth key form the decompiled eufy app, it can be ignored.

This looks good. Did you use opus of sonnet on this one?

It looks Ike it's found some stuff that I didn't know about 👍

I'll review properly on Monday

[thjont]

I got the Pro plan, which I think is restricted to Sonet.

First thing is we could use a symlink from AGENTS.md to CLAUDE.md

And make it slightly more generic when it comes to LLMs.
