fix: recover when sqlite parent directory disappears

[giscebot]

Summary

• expand literal ~ in the configured SQLite queue path
• recreate the database parent directory before every connection, allowing long-running workers to recover if the state directory disappears
• initialize a fresh queue schema when the database disappeared with its parent, so recovery does not fail later with no such table
• cover user expansion and end-to-end claim_next() recovery with focused tests

Closes #18.
Closes #22.

Tests

• /home/openclaw/.pyenv/versions/erp3/bin/python -m pytest -q tests/test_queue.py (16 passed)
• /home/openclaw/.pyenv/versions/erp3/bin/python -m pytest -q (158 passed, 1 dependency deprecation warning)

Traceability

No TASK id was supplied. ERP task creation is unavailable in this runtime because no ERP URL/database/token configuration is present.

Verified the sqlite parent-directory recovery is already present in commit (). The regression test now covers the missing-parent case by deleting the parent directory and asserting the queue recreates it and initializes the schema.

I tried to re-run the targeted test locally, but this checkout has no usable pytest installation ( is absent on PATH and has no module), so I could not execute the test suite in this environment.
