Add Bare agent suspend balance repro

[coreymartin]

Summary

Adds a Bare repro script for the agent suspend/resume balance behavior in spark-bare-app, including explicit bare-http1 / bare-https dependencies so the example resolves agent implementations that expose suspend() and resume().

The script now defaults to Nam's direct-await case:

• enable SDK logging at TRACE by default
• suspend the Bare HTTP/HTTPS agents
• call await wallet.getBalance() directly while suspended, without wrapping that suspended balance call in Promise.race

The earlier watchdog comparison flow is still available with REPRO_MODE=race.

Included captured logs:

• repro-agent-suspend-balance-direct.log: direct suspended getBalance() rejects immediately with AGENT_SUSPENDED, then cleanup exits normally.
• repro-agent-suspend-balance-direct-no-cleanup.log: direct suspended getBalance() rejects immediately, but without cleanup the process remains alive on the background stream until the external timeout kills it.
• Earlier race-mode logs are retained for comparison.

Findings

I was still not able to reproduce a foreground getBalance() call hanging forever. With SDK TRACE logging enabled and no Promise.race around the suspended balance call, the captured direct log shows BareHttpTransport failing request setup with AGENT_SUSPENDED and getBalance() rejecting in the same tick range.

The process-liveness issue remains reproducible: the no-cleanup direct run prints repro script completed, then continues receiving subscribe_to_events chunks until the external 45s timeout exits with code 124.

Public

Adds a public Bare repro script and captured logs for agent suspend/resume balance behavior. No production SDK behavior is changed.
