26.6.1

KOS2 26.6.1 — Ollama-only refactor. Finishes the cloud-zoo cleanup: KOS2 now ships a single local-first provider story with a much smaller, cleaner bundle.

Ollama-only refactor

• Removed all remaining cloud LLM providers; chat and embedding providers are now only Ollama (local) and OpenAI-compatible (for local self-hosted endpoints).
• Removed the Copilot Plus subscription paradigm entirely — every feature is available without any license or paywall.
• Renamed the misleading BrevilabsClient to KOS2ToolsClient; it was already a local shim (URL/web fetch, Ollama Cloud web search, local document handling) with no api.brevilabs.com calls.
• Kept the local Miyo self-hosted vector backend and the optional self-host web-search / transcript integrations.

Internal rebrand

• Renamed the chat view, agent chain runner, settings tab, and onboarding/settings surfaces from Copilot*/CopilotPlus* to KOS2*/Ollama*.
• No migration needed — the chat view type was already kos2-chat-view.

Dependencies, bundle, and security

• Removed crypto-js (cache hashing → zero-dependency FNV-1a; API-key encryption already used Web Crypto).
• Removed next-i18next (unused, but it transitively pulled the entire Next.js framework and ~20 high-severity advisories) plus koa, koa-proxies, @koa/cors, @huggingface/inference.
• Declared the previously-undeclared @langchain/classic dependency.
• main.js reduced from 5.3 MB → ~3.0 MB.

Notes

• Binary Office document parsing (Word / PowerPoint / Excel) is intentionally unsupported; text, Markdown, CSV, JSON, XML, and HTML are handled locally.
