0.15.0 - Concurrency Races Everything Around Me

Important note: prior to this release, it was possible for a task to re-add itself during its own execution with docket.add(...), but that ability exposes a race condition. Instead, in that scenario, you'd do a docket.replace(...) instead (see the test changes in #209 for the example). Also, if you have tasks that reschedule themselves (by key) this way, try using a Perpetual dependency instead, it may be more ergonomic.

What's Changed

• Add docket.testing module for task scheduling assertions by @chrisguidry in #204
• Use stdlib uuid7 on Python 3.14+, fall back to vendored implementation by @chrisguidry in #205
• Fix replace() to register unregistered functions by @chrisguidry in #207
• Allow task registration before entering context manager by @chrisguidry in #208
• Fix duplicate task execution race condition by @chrisguidry in #209
