docs(plugin-directory): add @avasapp/rozenite-plugin-ably

[crockalet]

Description

Adds a community Rozenite plugin to the plugin directory:

• @avasapp/rozenite-plugin-ably — an Ably Realtime inspector: attached channels with their subscriber counts and error reasons, a filterable event stream, and a payload viewer that parses Ably's JSON-string payloads into a searchable tree.

The Network Activity panel already shows websocket frames; this answers the Ably-shaped questions instead — which channels are attached right now, which ones silently went suspended, which feature subscribed to a given channel, and what was actually inside a message.

Appended to plugin-directory.json with the standard npmUrl + githubUrl fields. The package is published on npm and the repository is public.

Related Issue

N/A — follows the documented "open a pull request to contribute your plugin" flow for the plugin directory, as in #291.

Context

Docs-only. One entry appended to plugin-directory.json; no packages, workflows, or website code touched, so no version plan is required.

Implementation notes that may be of interest, since they lean on Rozenite internals:

• The plugin instruments any Ably.Realtime client structurally, so it has no ably dependency and works against whatever ably-js version the host app has.
• It never wraps the app's own message listeners — content is observed through a separate passive subscription, so a bug in the plugin cannot stop the app receiving a message — and the passive subscription is installed lazily, only once the app has itself subscribed, so it never causes an attach the app did not ask for.
• Optional protocol-frame capture uses client.setLog({ level: 4 }), which is present at runtime but absent from ably-js's public typings, so it is feature-detected and off by default.

Testing

• @avasapp/rozenite-plugin-ably@0.1.0 installs from npm and is discovered by Rozenite 1.13 ([Rozenite] Loaded 1 plugin(s)).
• Verified end-to-end on an iOS 26.5 simulator via a bundled example app that drives a fake Ably client through the real hook and bridge, and separately in a production React Native monorepo across three apps.
• Both URLs in the new entry resolve, and plugin-directory.json still parses (22 entries).
