Add a new `snippets/claude_debug_helper.py` to
provide a programmatic interface to `tractor.pause()` debugger
sessions for incremental data inspection matching the interactive UX
but able to be run by `claude` "offline" since it can't seem to feed
stdin (so it claims) to the `pdb` instance due to lack of ability to
allocate a tty internally.
The script-wrapper is based on `tractor`'s `tests/devx/` suite's use of
`pexpect` patterns for driving `pdbp` prompts and thus enables
automated-offline execution of REPL-inspection commands **without**
using incremental-realtime output capture (like a human would use it).
Features:
- `run_pdb_commands()`: batch command execution
- `InteractivePdbSession`: context manager for step-by-step REPL interaction
- `expect()` wrapper: timeout handling with buffer display
- Proper stdin/stdout handling via `pexpect.spawn()`
Example usage:
```python
from debug_helper import InteractivePdbSession
with InteractivePdbSession(
cmd='piker store ldshm zecusdt.usdtm.perp.binance'
) as session:
session.run('deduped.shape')
session.run('step_gaps.shape')
```
