fix(moments): the tools import the delivery module, and the tool-list cache leaves the swept directory (milestone 458 step 4a, #4922)

Two guards caught 7865313:

- test_mcp_tool_processes reads every coroutine in a tool module's
  namespace as a tool, and a name-imported attach_moment_rules looked
  like one. All seven modules now call moment_delivery.attach_moment_rules,
  and the parity guard accepts the attribute form.
- The session-ledger convention: a file in a swept directory must be a
  .ids ledger. The tool-list cache describes the install, not the
  context, so it moves to its own directory, scribe-moment, where a
  compaction does not sweep it.
