Patch Changes

• #14882 ab9132d Thanks @petebacondarwin! - Report built-in modules that a Worker's compatibility settings don't provide as module errors, instead of crashing workerd

  Previously, a Worker whose module graph statically reached a compatibility-gated built-in that wasn't enabled — for example import "node:child_process" without nodejs_compat — took down the runtime with *** Received signal #11: Segmentation fault before any test ran. Vitest reported only Worker exited unexpectedly, naming neither the module nor the file that imported it, which made the cause very hard to find. The import didn't even have to be called; being reachable from the entrypoint was enough.

  The module fallback service answered these specifiers with a redirect to the modules root, but workerd already resolves node:/cloudflare:/workerd: specifiers there, so the redirect pointed back at the module workerd was in the middle of resolving and it recursed until the stack overflowed. Such a specifier only reaches the fallback service when workerd's own registry has already missed, so it's now reported as not found: workerd raises No such module "node:child_process", matching what wrangler dev does for the same Worker. The accompanying pool error names the module and points at compatibility flags rather than suggesting you bundle it, which can't help for a module built into the runtime.
