Add kaydet

Add kaydet - a queryable personal database and terminal diary.

Hidden Gem submission (28 stars, below 100 threshold):

Kaydet is a unique CLI tool that combines a plain-text terminal diary with SQLite FTS5 full-text search, structured metadata queries (key:value with numeric comparisons), tag management, todo tracking, file attachments, and a built-in MCP server for AI assistant integration.

Why it's awesome:

• Python-first: 100% Python, 197 tests, production-ready
• Unique value proposition: Not just a diary - a queryable personal database with SQLite backend
• Active development: 3+ years of consistent commits, latest release v0.38.1 (July 2026)
• Well documented: Comprehensive README, file format spec, query syntax docs, contributing guide
• AI integration: Built-in MCP server exposes 13 tools to Claude Desktop and other AI assistants
• Real-world usage: 28 GitHub stars, Homebrew package, PyPI package with Trusted Publisher publishing

Key differentiator: Unlike most note-taking CLIs, kaydet stores entries as plain text files (git-friendly, no lock-in) while maintaining a SQLite FTS5 index for fast full-text and metadata search.

@vinta I find this project is a legitimate Hidden Gem, what do you think?
