fix(sdk): repair broken __all__ list — new constants/func escaped list boundary

Browse Source 
The PR accidentally embedded the new module-level constants and
make_idempotency_key function inside the __all__ list literal,
causing a SyntaxError. Fix closes the list after the existing exports
and adds make_idempotency_key + verify_plugin_sha256 as proper string
entries (compute_plugin_sha256 was removed in this PR so it is omitted).

Combines the task text with the current wall-clock minute to produce
a SHA-256 hex digest. Rounding to minute-level means two container
restarts within the same minute that send the same task string will
share the same key, preventing the platform from processing a duplicate
delegation. A different minute (or a different task string) yields a
different key.
Args:
task_text: The task description string being delegated.
Returns:
A 64-character hex string (SHA-256 digest).
