docs(skill): add the magic_sentry plugin reference

[anilcancakir]

Adds the skill's reference page for magic_sentry, published as 0.0.1 today, so an agent adopting it reads the same kind of page the other six plugins have. The page reaches the fluttersdk/ai registry with magic's next release.

What changes

• skills/magic-framework/references/plugin-sentry.md (new, stamped magic_sentry v0.0.1): installation and floors, the boot order (MagicSentry.run before Magic.init, one zone, why the config is not a magic config factory), SentryServiceProvider's parameters and the four things its boot() wires in order, SentryNetworkInterceptor's event vs breadcrumb split with the endpoint normalisation, fingerprint and per-session dedupe, SentryUserContext, ReportsBreadcrumb events, the published .env keys, and a gotchas table.
• SKILL.md: a row in the section 11 plugin table, -sentry.md in the reference index, magic_sentry in the when_to_use trigger line; version: 0.1.51 to 0.1.52 and the body stamp's skill version with it (magic 0.0.22 unchanged).
• CHANGELOG.md: an [Unreleased] ### Added entry.

Verified against

Every symbol on the page was read from magic_sentry at e40ade1 (0.0.1): lib/src/magic_sentry.dart (run, installErrorWidgetBreadcrumb), lib/src/sentry_service_provider.dart (constructor, boot() order, the static breadcrumb remover), lib/src/sentry_network_interceptor.dart (dispositionFor, normalizeEndpoint, reportedFailures, the fingerprint), lib/src/sentry_user_context.dart, lib/src/event_breadcrumbs.dart, assets/stubs/install/sentry_config.stub and install.yaml. ReportsBreadcrumb and Event.listenAny were read from this repo (lib/src/events/reports_breadcrumb.dart, lib/src/facades/event.dart:57), and the observer refusal from MagicRouter.addObserver's StateError.

Looks correct: docs-only addition, consistent with the repo's own source and conventions.

No findings. This adds references/plugin-sentry.md plus the matching SKILL.md table/index/trigger-line entries and a CHANGELOG.md entry, following the same shape as the other plugin reference pages (compared against plugin-notifications.md) and the post-change sync rules in CLAUDE.md. The claims that touch this repo's actual code check out: ReportsBreadcrumb (lib/src/events/reports_breadcrumb.dart) and Event.listenAny (lib/src/facades/event.dart:57) exist as described, and MagicRouter.addObserver (lib/src/routing/magic_router.dart:179) does throw a StateError once the router is built, matching the "wire the observer in boot()" gotcha. The magic ^0.0.22 floor claim is also consistent with plugin-deeplink.md's existing statement about the same contract. The magic_sentry package itself isn't in this repo, so its internal symbols (SentryServiceProvider, SentryNetworkInterceptor, etc.) weren't independently verifiable here, only the repo-side claims were checked.

Tests

Docs-only change; no lib/ code touched, so no test coverage applies. Internal links/anchors are checked by CI.
