Add Mistral Vibe support for Agency agents (#658)

* Add Mistral Vibe support for Agency agents

- Add Mistral Vibe entry to tools.json with proper configuration
  (id, label, kebab, format, installKind, dest, detection, version)
- Implement convert_vibe() function in convert.sh for Mistral Vibe's format
  - Generates TOML agent configuration files (~/.vibe/agents/<slug>.toml)
  - Generates markdown prompt files (~/.vibe/prompts/<slug>.md)
  - Each agent gets agent_type and system_prompt_id (no hardcoded active_model)
- Add install_vibe() function in install.sh with full feature support
  - Copies both agent TOML and prompt MD files
  - Supports division/agent filtering and environment variable overrides
  - Uses VIBE_HOME environment variable for custom install paths
- Add Mistral Vibe detection and tool labeling
- Add Mistral Vibe to all necessary case statements and arrays
- Update README.md to document Mistral Vibe support
- All changes validated with scripts/check-tools.sh

Mistral Vibe uses a two-file approach per agent:
- ~/.vibe/agents/<slug>.toml for agent configuration
- ~/.vibe/prompts/<slug>.md for system prompts

Users can specify active_model in their agent TOML files or rely on their
Vibe configuration default model.

Usage: ./scripts/install.sh --tool vibe [--division X] [--agent Y]

* Address PR #658 review feedback: add .gitignore, README, and fix icon

- Add integrations/vibe/README.md documenting the Mistral Vibe integration
- Update .gitignore to ignore integrations/vibe/agents/ and prompts/
- Update convert.sh usage() to include vibe in the tool list
- Fix tools.json: change vibe icon from 'mistral' to null (no mistral.svg)
- Bonus: update vibe accent color from #FF69B4 to #FA520F (Mistral brand orange)
