Problem

#57175 stopped the DigitalOcean router poll because it ran in every open folder every 5 minutes, even when signed out, and reloaded the catalog on every tick. Since then, a router created mid-session only shows up after a restart or re-auth.

Change

The refresh is back, every 5 minutes, but only while signed in, and each tick is quiet unless the routers actually changed.

on startup, or when the DigitalOcean account changes:
    load routers
    if signed in (and the token hasn't expired):
        start a 5-minute loop (once per folder)
    otherwise:
        stop the loop

each tick:
    folders on the same token share one fetch per 5 minutes
    reload the catalog only if the router list changed

• Signed out: no timer and no requests.
• Folders signed in with the same token share one request per 5 minutes. The cache is keyed by the process HTTP client, so each test's client keeps its own.
• An unchanged router list no longer reloads, so it sends no provider.updated.

Out of scope

• The same refresh for Copilot, GitLab, Modal and Azure. They still fetch only at startup and on account changes.

Tested

• Existing DigitalOcean tests pass.
• I checked a throwaway scenario (not committed) with two plugin instances on one HTTP client:

Step	Requests	provider.updated
Signed out, 30 min	0
Sign in	1
Signed in, 15 min, same routers	+3 total (one per 5 min, shared)	0
Router added, +5 min	+1	new router shows up
Sign out, then 30 min	0

No blocking problems found. Polling runs only while signed in and stops when you sign out or the token expires. A router added mid-session shows up on the next tick, and an unchanged router list no longer reloads the catalog.

How I checked: I ran a throwaway scenario with a mocked HTTP client and a simulated clock. Signed out, it made no requests. Signed in, it made one request per 5 minutes, and a new router appeared after one tick. Signing in again with a new token and the same routers kept them in the catalog. The existing DigitalOcean tests pass (10/10), and tsc -b for packages/core passes.

Public API: unchanged. This is an internal change to the plugin only.

No concerns.
