(janitor/dead-code): remove orphaned SSEStreamProcessor in auto-fix-infra

[kilo-code-bot]

What was deleted

services/auto-fix-infra/src/services/sse-stream-processor.ts — a single 204-line file containing the SSEStreamProcessor class (a generic Server-Sent Events parser/buffer manager) plus two module-private type declarations (StreamEventHandler, StreamMetrics).

Evidence it was unreachable

• Symbol search: SSEStreamProcessor has zero references outside its own file (only its definition and internal method calls).
• Path search: no import specifier matches sse-stream-processor (relative, package subpath, or @/ alias) anywhere in the repo, including .ts, .tsx, .js, .mjs, .json, and .jsonc.
• No barrel: services/auto-fix-infra/src/services/ has no index.ts; nothing re-exports the module.
• No in-service consumer: src/index.ts (Worker entry) and src/fix-orchestrator.ts import only ./services/prompt-builder and ./services/cloud-agent-next-client. The actual cloud-agent client (cloud-agent-next-client.ts) talks to cloud-agent-next over HTTP fetch (prepare/initiate), not SSE.
• No tests: no test file references it.
• No side effects: the file has no imports and no module-level executable statements (only type declarations and a class), so deleting it cannot remove any initialization behavior or side effects.
• External consumer: Kilo-Org/kilocode (cloned and searched) contains no reference to SSEStreamProcessor or sse-stream-processor.

Dynamic and configured entry points checked

• wrangler.jsonc: main is src/index.ts; the only Durable Object binding is AutoFixOrchestrator; no cron/queue/RPC/alarm/workflow binding references this module.
• No dynamic import(...) references the path.
• Not a Next.js convention file (this is a Cloudflare Worker service, not apps/web).
• Not referenced in CI, scripts, or package.json scripts.
• Git history shows the file was only ever moved in the monorepo restructure (refactor: restructure repo into apps/services/packages monorepo #1315) and never imported since.

Contract and compatibility considerations

• kilo-auto-fix-worker is a private: true package with no published exports; SSEStreamProcessor is not in its surface.
• No persisted data, migrations, or rollback concerns: the file is a stateless parser with no database or DO wiring.
• Removing it does not change the Worker's HTTP routes or the AutoFixOrchestrator Durable Object contract.

Validation performed

• pnpm --filter kilo-auto-fix-worker typecheck — passes (no errors).
• pnpm --filter kilo-auto-fix-worker lint — 0 warnings, 0 errors.
• pnpm --filter kilo-auto-fix-worker test — 1 passed.
