Upgrades the media primitive and all of its workspace dependencies to Solid.js 2.0.0-beta.7. The package is bumped to 3.0.0 as a breaking major release.

What changed

@solid-primitives/media

• isServer import moved from solid-js/web → @solidjs/web
• Peer deps updated to solid-js@^2.0.0-beta.7 and @solidjs/web@^2.0.0-beta.7
• Tests cleaned up — onMount removed, assertions made synchronous
• README examples updated for Solid 2.0 patterns (class array form, split createEffect)

@solid-primitives/utils

• onMount → onSettled in createHydratableSignal
• sharedConfig.context → sharedConfig.hydrating for hydration detection
• equalFn → isEqual, INTERNAL_OPTIONS uses pureWrite: true (was internal: true)
• AccessorArray<T> removed (gone from Solid 2.0) — replaced with Accessor<T>[]

@solid-primitives/static-store

• getListener → getObserver, { internal: true } → { pureWrite: true }
• Explicit batch() calls removed — Solid 2.0 batches automatically on microtasks
• sharedConfig.hydrating + onSettled in createHydratableStaticStore

@solid-primitives/rootless

• batch removed from createRootPool, sharedConfig.hydrating in createHydratableSingletonRoot

@solid-primitives/event-listener

• All isServer imports updated to @solidjs/web
• createEventListener and createRenderEffect converted to the required Solid 2.0 split compute/apply pattern — listeners now attach in the apply phase with cleanup returned as a function
• eventListener directive likewise converted; no longer uses onCleanup inside an effect

Notes

• @solidjs/web@latest points to experimental.0 which is incompatible with beta.7 — the correct version is @solidjs/web@2.0.0-beta.7 (the next dist-tag).
• All 11 tests pass (9 browser, 2 SSR).
