feat: add Freebuff provider and fix dompurify security vulnerabilities

- Add Freebuff provider integration (executor, registry, OAuth, usage tracking)
- Upgrade monaco-editor to ^0.56.0
- Add dompurify ^3.4.13 with override to fix security vulnerabilities
- Add Freebuff provider icon and test files

/**
* Freebuff Executor — OpenAI-compatible chat completions on
* https://www.codebuff.com/api/v1/chat/completions (the Codebuff/Freebuff backend).
*
* Wire shape mirrors the official CLI exactly. The CLI (Vercel AI SDK with the
* codebuff openai-compatible provider) builds `providerOptions.codebuff` =
* { codebuff_metadata, provider } and the provider spreads those entries at
* the TOP LEVEL of the request body — i.e. the body is:
* { model, messages, codebuff_metadata: { run_id, client_id, cost_mode,
* freebuff_instance_id? }, provider: { allow_fallbacks } }
* NOT nested under a `codebuff` object (the backend rejects the nested shape
* with 400 "No runId found in request body").
*
* The run_id is not a free-form uuid: the backend resolves it against its
* agent-run store and rejects unknown ids with 400 "runId Not Found". So every
* chat request first registers a run via POST /api/v1/agent-runs
* ({ action:"START", agentId, ancestorRunIds:[] }) → { runId }, and that id is
* what goes in codebuff_metadata.run_id. The free tier additionally gates on a
* session: POST /api/v1/freebuff/session with an `x-freebuff-model` header
* claims a row (bound to one model, ~1h); its instance id must ride along as
* codebuff_metadata.freebuff_instance_id.

/**
* Freebuff — the free, ad-supported coding agent by Codebuff (freebuff.com).
*
* The Freebuff CLI (github.com/CodebuffAI/freebuff) is an interactive TUI that
* talks to the Codebuff/Freebuff backend. Two hosts are involved:
* - login flow (freebuff mode) runs on https://freebuff.com
* POST /api/auth/cli/code {fingerprintId} → { loginUrl, fingerprintHash, expiresAt }
* open loginUrl in browser, then GET /api/auth/cli/status until {user}.
* (The server echoes the request host into loginUrl, so calling
* freebuff.com yields freebuff.com/login?auth_code=… exactly like the
* official CLI — www.codebuff.com would yield the wrong link.)
* - LLM traffic goes to the OpenAI-compatible endpoint on
* https://www.codebuff.com/api/v1/chat/completions
* (freebuff.com does NOT serve /api/v1/* — it 404s with the SPA shell.)
*
* Both hosts share one backend: the authToken obtained via the freebuff.com
* login validates against www.codebuff.com (Bearer auth). The request body
* must carry the CLI's `codebuff` provider block
* (`codebuff_metadata.run_id/client_id/cost_mode`) — injected by
* executors/freebuff.js. cost_mode:"free" is what admits a session on the free
* (country-gated, session-limited) tier instead of billing credits.
