[FEATURE] Bulk-create/edit a scheduled Routine across multiple repositories at once

Summary

Setting up a recurring scheduled Routine today is a one-repo-at-a-time process. For anyone running the same kind of routine (e.g. a daily health/status check) across many repos, there's no way to configure it once and apply it to a set of repos in one action. Please add bulk creation/editing of Routines across multiple repositories.

Current behavior

Each Routine is created against a single project directory. Running the same conceptual check (e.g. "daily repo review") across N repos means manually creating N nearly-identical Routines, one at a time, each with its own schedule and prompt to set up individually.

Motivation

Anyone maintaining several active repos who wants the same kind of recurring check on all of them (dependency audits, health checks, "anything broken overnight" reviews) has to repeat the entire Routine-creation flow per repo. This scales linearly with repo count and makes it tedious enough that most people just... don't bother rolling it out everywhere, even when they'd want to.

Proposed behavior

1. A bulk-create flow: define a Routine's prompt/schedule once, then select multiple target repos/directories to apply it to.
2. Each target gets its own independent Routine instance (own schedule, own session history) — this is about the authoring step, not merging execution across repos.
3. Bulk-edit: updating the shared prompt/schedule template optionally propagates to all repos that were created from it (with a diff/preview before applying, so per-repo customizations aren't silently clobbered).
4. Bulk-disable/delete for cleanup when a batch of routines is no longer needed.

Why it matters

• Removes the friction that currently discourages rolling out useful recurring checks across an entire portfolio of repos.
• Companion to #79080 (consolidated digest) and #79085 (silent-stop alerting) — those help once Routines exist across many repos; this helps get them set up in the first place.
