Motivation

• Prevent unbounded webhook delivery fan-out from duplicating full post payloads into SQLite and exhausting disk capacity by adding global queue limits and prompt cleanup.

Description

• Add webhook_max_queued_deliveries configuration and load/validate it in Config so the delivery queue has a tunable global row cap. (src/msgd/config.py, deploy/etc/msg-lmm-best/msg.conf)
• Enforce a global queue quota in Store.queue_webhook_event by checking current delivery row count and total serialized delivery bytes (against cfg.max_storage_bytes) before inserting new delivery rows. (src/msgd/store.py)
• Remove successful deliveries and deliveries that exhaust retry attempts immediately from webhook_deliveries to reclaim queue capacity instead of retaining them for days. (src/msgd/store.py)
• Surface and document the new queue limits in rendered metadata and README. (src/msgd/render.py, README.md)
• Add a regression unit test that exercises row-count limiting, payload-byte limiting, successful-delivery cleanup, and retry-exhaustion cleanup. (tests/test_webhooks.py)

Testing

• Ran static checks with uv run ruff check . which passed.
• Ran focused unit tests with uv run python -m unittest tests.test_webhooks -v and uv run python -m unittest discover -s tests -q, all executed tests passed (4 focused webhook tests passed; full test run: 146 tests passed, 1 skipped).
• Verified repository formatting and linting with uv run ruff format as part of the test workflow.
