the README was upstream's, wordmark and all

This repo shipped Sentry's README verbatim: their wordmark hotlinked from
sentry-brand.storage.googleapis.com, four screenshots served out of
getsentry/sentry, their SDK index, their Discord, their Transifex.

The FSL grants copying and modification. It grants no trademark rights, and none
of the usual open-source licenses do. So carrying upstream's wordmark as this
project's masthead was the one part of the fork that was not ours to do —
de-branding is a licensing requirement here, not a style preference.

LICENSE and NOTICE stay exactly as they are. Those are the parts the license
does require, and they are the reason the fork is legitimate; the rebrand
removes the mark and keeps the attribution, which is the whole distinction.

The README now says what Sentinel is and states the one fact a reader needs:
it speaks the Sentry wire protocol, so existing client SDKs report to it with
nothing changed but a DSN.

-# What's Sentry?
+# Sentinel
 
-Sentry is a developer-first error tracking and performance monitoring platform that helps developers see what actually matters, solve quicker, and learn continuously about their applications.
+Error tracking and performance monitoring for the Hanzo cloud. Sentinel receives
+events from your applications, groups them into issues, and tells you which ones
+are new, regressed, or getting worse.

+Sentinel speaks the **Sentry wire protocol**, so the existing ecosystem of client
+SDKs reports to it unchanged — a DSN pointing at your Sentinel instance is the
+only configuration difference. There is no Sentinel-specific SDK to adopt, and
+none is planned; the protocol is the interface.
