Pull request overview
Adds a configurable Weights & Biases run name with {date} and {seed} placeholder substitution, replacing wandb's previous auto-generated random names. Opt-in via a new --run-name CLI flag / run_name config key, with the existing single-agent cluster config updated to use the new feature.
Changes:
- New
--run-nameCLI flag inpufferl.py(defaultNone, preserving prior auto-name behavior). WandbLogger.__init__formats{date}(launch-timeYYYY-MM-DD) and{seed}(fromargs.train.seed) into the run name before callingwandb.init(name=...).single_agent_speed_run.yamlopts in withrun_name: "{date}_seed{seed}".

…e_agent yaml
wandb.init() previously did not set name=, so wandb assigned random names
like "flowing-wind-34". Adds a --run-name CLI flag (top-level config key)
that pufferl's WandbLogger renders against {date} (launch-time YYYY-MM-DD)
and {seed} (args.train.seed) placeholders before passing to wandb.init.
Default is None — wandb auto-name preserved. The single-agent speed-run
yaml opts in by setting run_name: "{date}_seed{seed}", giving identifiable
runs like 2026-05-31_seed0 without per-seed launcher logic.

Summary
wandb.init() previously did not set a
name=, so wandb assigned random display names like "flowing-wind-34". This PR plumbs a--run-nameconfig key through pufferl and has the single-agent launcher script construct a per-seed name like2026-05-31_seed0.
