Improving `search`

[fredjaya]

Priority:

• Need robust search algorithm

Rest:

• Convert output to Rich Standardise output rendering with Rich library for consistent UI/UX across all commands #3
• Only returns 10 tools? Should be e.g. 10, then see more
• Add next step instructions e.g. shelley-bio find to see info, shelley-bio build to install, shelley-bio versions
