Subject: [PATCH] fix(bud): show "Run estimation" button in empty-state for
 MCP-created BUDs

When a BUD is created via the remote MCP `create_bud` tool, the caller
supplies `requirements_md` directly, so the PRD agent never runs. The
PRD agent's completion handler is the only place that triggers the first
`estimate_bud_dates` snapshot, so MCP-created BUDs land on the
"No estimates yet" empty state with no way to populate it from the UI.

Surface a manual "Run estimation" button in the empty-state branch of
`BUDEstimateTimeline.vue` that emits the same `recalculate` event the
populated header already uses. The existing
`POST /v1/buds/{id}/estimates/recalculate` endpoint is first-run safe;
no backend change required.
