docs: add mid-2026 update blog post

[jonathannorris]

Summary

Mid-2026 community update, covering the window since the KubeCon EU 2026 recap:

• Platform-native feature flags: Datadog, Vercel, Cloudflare, Google Cloud, and Mixpanel all launched flag services that build on or expose OpenFeature
• New vendors: Featureflip and Switchbox shipped their first providers, and Flagsmith, GO Feature Flag, and Unleash expanded language coverage
• Nicklas Lundin joining the Technical Committee
• Specification v0.9.0, our first spec release since v0.8.0 in March 2024
• Also shipped: isolated API instances across five SDKs, the flagd DISABLED semantics rollout, 64-bit integer support in the JVM SDKs, new providers, and three breaking changes
• Where we could use help: framed around cross-cutting efforts (v0.9.0 compliance, the conformance suite, fractional hashing, OFREP SSE, multi-provider parity) rather than one-off issues

In `@blog/2026-08-12-mid-2026-update.md`:
- Around line 22-23: Update the Datadog bullet’s “eight languages” wording to
describe eight OpenFeature integrations across server and client platforms,
since React, iOS, and Android are not languages. Keep the listed server-side
languages and client-side integrations unchanged.
- Around line 97-98: Update the rollout statement to refer to five SDKs or five
core SDK libraries instead of five flagd cores, while preserving the linked
projects and the surrounding explanation.
- Around line 52-54: Update the Unleash provider statement to say six official
providers and list Node.js, PHP, Python, Ruby, Rust, and Swift, removing Android
unless an authoritative source confirms a seventh provider.

- Line 125: Update the OpenFeature Operator release note so native sidecar
support and the Kubernetes 1.29 minimum are attributed to v0.9.1 or a later
release, not v0.9.0, while retaining the v0.9.2 release link and existing
factual context.
