Claude Bot 4d4ea8ca15 fix(stack): disable TCO for Node.js-compatible stack traces ...

Disable tail call optimization (TCO) by default to ensure all
intermediate stack frames are preserved in Error.prepareStackTrace
call site objects.

V8/Node.js doesn't implement proper tail calls, so the Node.js
ecosystem expects all stack frames to be present. Libraries like Nx,
node-depd, and others use Error.prepareStackTrace to analyze call
stacks and break when frames are eliminated by TCO.

This fixes compatibility with tools that rely on accurate stack
traces for:
- Detecting recursion patterns
- Finding the calling module
- Debugging and profiling

Users who need TCO can re-enable it with BUN_JSC_useTailCalls=1.

Fixes #25738
