Add YYLO to Productivity Tools

[InsightFactoryAPP]

Summary

Adds YYLO — application name: YYLO; category: Productivity Tools; open source project page: https://github.com/yylo-dev/yylo — as a single line at the end of the Productivity Tools section.

YYLO is a command-line orchestrator for coding agents, repeatable workflows, and receipt-backed repository changes. It is for developers who want a quick agent loop and for project operators who need typed task, validation, merge, and release-readiness boundaries: each task runs in a dedicated branch/worktree, and the merge queue owns risk-based review of agent-made changes. MIT-licensed, installable via npm (@yylo/cli).

Why Productivity Tools

The section scope — "All the tools, services which increase productivity, developer velocity and developer experience" — is where YYLO fits best: it is a terminal-native developer-velocity tool (in the neighborhood of claws, Telert, tenv). It is deliberately not filed under Automation & Orchestration or CI & Delivery since it neither provisions infrastructure nor is a CI server. If you see a better home (e.g. Code review, given the merge queue's review role), I'm happy to re-file.
