master now ships the reminder stack as the optional
`@deepseek-ai/dsh-experimental-schedule-bundle`; this branch keeps the
preset-level ownership beside it.
Resolutions:
- The Host rows keep master's `disabled: true`. The optional bundle switches
`schedule` and `ui-schedule` on and no longer `time-context`: the clock row
is preset-level, so flipping the Host row as well would mount the plugin in
two scopes and write two readings per step.
- `standard`, `cordis`, and `ptc` declare `preset-time-context` and
`tool-schedule`; `minimal` declares neither.
- `tool-schedule` injects `tools` and resolves `schedule` per scope through
`ctx.inject`, so the row stays valid but produces no tools while the service
is off, and produces them once the bundle mounts it.
- The assembled-Web Schedule spec keeps master's bundle overlay and restates
the shipped `preset-standard` row instead of the deleted fixture, because a
top-level patch cannot reach a plugin a preset declares.
- Documentation and Agent Notes describe both layers; the note master archived
stays frozen with its manifest hashes.
