Please post a sample dump :)

Pull request overview

Adds a human-readable (“plain text”) post-mortem dump alongside the existing JSON dump for Thunder worker-pool internals, improving debuggability of crashes/hangs without requiring JSON parsing.

Changes:

• Build a readable text representation of worker-pool pending requests and per-thread callstacks during Server::DumpMetadata().
• Persist the readable dump to ThunderInternals.txt next to the existing ThunderInternals.json post-mortem output.
