xiaoju 3709fae5e1 fix: /run/{name} → 302 redirect, bypass CF same-zone fetch limitation

CF Workers cannot fetch() other workers on the same .workers.dev zone.
This caused all /run/{name} routes to return Cloudflare's HTML 404
instead of proxying to the sub-worker.

Fix: replace inline fetch() proxy with a redirect-based approach:
- Default (browser/curl): 302 redirect to sub-worker URL
- Accept: application/json: return JSON with {url, capability, cold_start}

LRU bookkeeping (page-in, access count) still happens in Sigil before
the redirect, so cold capabilities are warmed up transparently.

New backend method: resolveInvoke() — same LRU/page-in logic as invoke()
but returns route info instead of executing the subrequest.

Sigil 🔮

Capability registry for Uncaged — LRU-managed Cloudflare Workers with abstract backend.

What is Sigil?

Sigil is the capability virtualization layer for Uncaged. It lets AI Agents deploy, invoke, and manage serverless capabilities (Cloudflare Workers) through a unified gateway, with LRU eviction to stay within platform quotas.

Architecture

One dispatch Worker (sigil.shazhou.workers.dev) as the unified entry point
KV-backed LRU for scheduling capabilities within CF Worker quota (~400 slots)
Abstract backend interface: WorkerPool ($5/mo) or Platform ($25/mo, Workers for Platforms)
Agent isolation via naming convention ({agent}--{capability}) + per-agent tokens
