perf(init): pre-compute directory listing before first API call

[betegon]

Summary

Sends a pre-computed directory listing with the first API call so the server can skip its initial list-dir suspend. Saves one full HTTP round-trip in the discover-context step.

Changes

Exports precomputeDirListing from local-ops.ts — reuses the existing listDir function with the same params the server would request (recursive, maxDepth 3, maxEntries 500). The wizard runner calls it before startAsync and includes the result as dirListing in inputData.

Companion server change: getsentry/cli-init-api#16

Test plan

• Init tests pass (bun test test/lib/init/)
• Lint passes
• End-to-end with local dev server
