Why: Bun/Deno/Cloudflare detection was hand-rolled in several places with slightly different checks (typeof Bun, process.versions.bun, inline userAgent === 'Cloudflare-Workers'). This adds isBun(), isDeno() and isCloudflareWorkers() to @sentry/server-utils (exported from the shared exports.ts, so they are also available from /no-diagnostic-channels) and uses them in server-utils, bun and astro.

They are functions rather than module-level consts so unused ones tree-shake cleanly and the check runs when called, not at import. Hono's runtime is now resolved per call instead of at module load.

How to review: Start with server-utils/src/utils/runtime.ts; the rest are mechanical call-site swaps.

Unsure about: Intentionally left alone:

  • remix (isCloudflareEnv): importing from server-utils, even /no-diagnostic-channels, pulls node:async_hooks into the Hydrogen build and broke the remix-hydrogen E2E, so remix keeps its local check
  • elysia (no server-utils dependency, didn't want to add one)
  • nextjs responseEnd.ts (nextjs doesn't import the server-utils barrel at runtime today)
  • server-runtime-injection/register.ts (runs at --import time and only pulls the orchestrion/config subpath, importing the main barrel there seemed risky)
  • bun/src/sdk.ts (typeof Bun is needed to narrow for Bun.version)

Build-time/static detection (export conditions or a define flag for Cloudflare) is a possible follow-up, not part of this PR.

Bun's own test suite wasn't run locally (no Bun binary in my environment); the change there is process.versions.bun → isBun().
