context/ — request-context extensions

Product plugins that add bounded model-visible request context without defining a tool or service. workspace-context is included by the default dsh-agent-spine-demo bundle and can be disabled through bundle config; time-context is opt-in.

Package	Role	ctx key
`time-context/`	Current time and elapsed-time system-prompt context	(none)
`workspace-context/`	`AGENTS.md`/`CLAUDE.md` workspace context loader	(listens on `agent/session-prefix` + `tools/post-execute`)

The workspace-context decision record explains its per-agent/session isolation and lifecycle split.
