Add agent-estate: autonomous work loop skill

[MercuriusDream]

What is Agent Estate?

Agent Estate is a Claude Code plugin that creates an autonomous work loop. It uses Claude Code's native hook system to intercept Stop events, re-inject prompts, and keep Claude working cycle after cycle with persistent memory via a ledger file.

Two modes:

• Perpetual (default) — no end condition, cycle after cycle until /agent-estate:stop
• Done (--done) — auto-stops when the task is complete

What makes it different?

• Native hooks — uses Claude Code's Stop event hook, not a bash wrapper
• Zero config — no PRD files, no task definitions, no tmux. Just /agent-estate:start
• Persistent memory — ledger + "Tell The Next Claude" handoff across sessions
• Minimal — ~400 lines total across the entire plugin
• Battle-tested — used to build Vibrowser, a from-scratch C++ browser engine in 287 autonomous cycles (100+ hours, 3,374 tests, zero failures)
