Fix cog templates to generate correct command name in docs and rewrite README

[Copilot]

Generated documentation showed Usage: cli instead of Usage: scrobbledb in all command help text.

Changes

• Updated 42 cog invocations across 15 doc files to pass prog_name='scrobbledb' to CliRunner.invoke()
• Regenerated all docs via poe docs:cli
• Completely rewrote README.md with comprehensive documentation

Technical Detail

Click's CliRunner.invoke() defaults to using the function name as the program name. The fix:

# Before
result = runner.invoke(cli, ["auth", "--help"])

# After  
result = runner.invoke(cli, ["auth", "--help"], prog_name='scrobbledb')

This changes the generated output from:

Usage: cli auth [OPTIONS]

To:

Usage: scrobbledb auth [OPTIONS]

README.md Rewrite

Expanded the minimal 17-line README into a comprehensive 240+ line document that includes:

• About Last.fm and Scrobbling: Detailed explanation of Last.fm, scrobbling, and the Last.fm API
• Why scrobbledb?: Clear value proposition (local backup, advanced queries, data portability, privacy)
• Origin: Credits Jacob Kaplan-Moss for the original lastfm-to-sqlite project
• Installation & Quick Start: Step-by-step setup and usage instructions
• Command Overview: All 15 commands organized by category with links to detailed documentation
• Example Workflows: Real-world usage examples for backup, analysis, and export
• Database Schema: Overview of the SQLite structure
• License: Notes Apache License 2.0 for both scrobbledb and the original project
• Links: Resources for Last.fm API, Libre.fm, and related projects

Original prompt

All of the generated docs show 'cli' at the top. That should be 'scrobbledb'. Please fix the cog text in each doc, then rerun the doc generation Poe task.
