Guide new installs to a first monitored workflow - #3227

Conversation
The web listener was bound inside the serving goroutine, so a taken port or an unreadable TLS certificate was only logged. server and start-all kept running with no web UI and no exit status. Serve now binds the listener and loads the TLS certificate before it starts serving, returns those failures, and returns any later serving failure. The startup log carries the real bound address and the URL that opens the UI. The server and start-all commands add a hint naming --port and DAGU_PORT when the port is already in use.
The Activity and Workflows empty states rendered CreateDAGModal, which renders nothing under the default All workspaces selection, so a new user read "Create one from scratch" with no button. Both now use CreateDAGButton, as the page header does, and CreateDAGModal is gone. The Workflows empty state also left its strings untranslated. The create dialog showed a raw regex and set a pattern attribute that is invalid under the v flag; both are gone and the name errors are translated. The Start dialog no longer shows "Parameters 0 fields" or a parameter-editing note for a workflow without parameters.
start-all enables the coordinator by default, so a second instance or another service on port 50055 made it exit with a bare "address already in use" error. The error now names the ways out: stop the other process, choose a port with --coordinator.port or DAGU_COORDINATOR_PORT, or disable the coordinator with DAGU_COORDINATOR_ENABLED=false. The failure stays fatal, since workers depend on a configured coordinator. The hint is limited to start-all; the standalone coordinator command keeps its message.
Retries were visible only in the step drawer, so a step that failed and recovered looked the same as one that passed the first time. The step table now shows "Retried N×" in the status cell on desktop and in the timing section on mobile.
start-all built DAG-run notification and incident monitors in both the web server and the scheduler on the same stores. The lease let only one pair deliver, so the other logged that the lock was held by another process, from inside a single process. The server gains WithoutNotificationMonitors, and start-all uses it because its scheduler already runs the same monitors with the same services and stores. Notification and incident APIs stay available. Separate server and scheduler processes are unchanged.
A fresh start printed only log lines, so a new user had to find the web UI address and the admin setup step on their own. Once the web server accepts connections, server and start-all print a short plain-text banner to stdout with the web UI URL, the admin setup link while no admin exists, the DAGs directory, and, on Community servers whose license is not managed by the environment, the free monitoring link. The banner is skipped in quiet mode, in headless mode, and when stdout is not a terminal, where the startup log line already carries the URL.
The first-launch examples only echoed text, so a new user never saw what an orchestrator adds over cron. example-03 also called itself a scheduled workflow while its schedule is commented out. example-06-retry-on-failure has a step that fails its first attempt and succeeds on its automatic retry, followed by a dependent step. The run history then shows a retried step. Each run uses its own artifacts folder, so every run repeats the demo. example-03 now says it runs on demand until its schedule is uncommented. Only new installs receive the new example.
The quickstart ran start-all with --dags . from wherever the user was, so stray YAML files such as docker-compose.yml loaded as broken DAGs. It also never mentioned the admin account the web UI asks for on first launch, or that a script install already runs a server on port 8080. The steps now use an empty folder, name the admin account step, and tell script-installer users to add workflows from the UI or the DAGs directory the installer printed.
Connecting to Dagu Console was reachable only from Plan & features, so a Community server rarely learned that its own alerts stop when it goes down. Admins of such a server now see a dismissible offer under an empty notification rules list and on the Overview of a workflow with an active schedule, and an External Monitoring link in the sidebar. Each points at /license#monitoring, which now scrolls to the connect card or, once connected, the monitoring card. Dismissal is stored per server and shared by every placement.
Homebrew printed nothing after install, so users did not learn how to start Dagu or that the web UI asks for an admin account. The script installers' success summary listed the service URL but not where workflow files go or that free monitoring is available. Both Homebrew formulas now print caveats with the service and foreground start commands and the admin account step. When the installers set up a background service, the summary adds the DAGs directory and the free monitoring page.
The postinstall script printed leftover debug values, and a failed fallback download left its promise rejection unhandled, so npm showed an unhandled-rejection trace instead of a clear failure. The debug output is removed. A failed download now prints one line naming the cause and makes the install exit with status 1.
A new install offered one line of guidance on the Activity tab. Users who can write workflows now see four steps there: run a workflow (the retry example when it exists), create one, put one on a schedule, and get alerted when something fails, through free monitoring from Dagu Console or a notification channel. A server whose first three steps are already done when the checklist is first evaluated never shows it, so upgraded servers stay quiet. Otherwise it shows until dismissed or until every step is done, and the outcome is stored per server. A failed request hides it without storing anything. While it loads or shows, an empty window reports only that no runs happened instead of the empty-state panels.
The offer repeated the connect card's long description. It now says what Dagu Console sends and that it is free for one server, which is all a reader needs to decide whether to open the setup page.

Review comments at @ui/src/hooks/useStoredValue.ts:
- Around line 46-52: Update useStoredValue’s read and setValue logic to keep a
per-key in-memory value, consult it before localStorage, and set it before
attempting persistence so failed writes still notify subscribers with the new
value. In the storage-event handler, clear the matching key’s fallback before
notifying subscribers so external changes take precedence.
Review comments at @ui/src/pages/license/index.tsx:
- Around line 88-96: Update the hash-scroll effect’s handledVisit tracking to
include the target element, and skip scrolling only when both locationKey and
target match the previously handled visit. This lets a remounted #monitoring
section scroll into view even when the location key is unchanged; also include
connecting in the effect dependencies so it reruns when a connection attempt
starts.

In a privacy-restricted browser the localStorage write fails silently, so dismissing the getting-started checklist or the monitoring offer did nothing. writeLocalStorage now reports whether the value was kept, and useStoredValue holds refused values in memory for the life of the page. A change from another tab still takes precedence.

The script installer wizard can create the first admin account, so the quick start should not tell every reader to create one on first launch.

What
Guide a fresh install from startup to a first monitored workflow, and fix the first-run bugs found on the way.
Startup
dagu serveranddagu start-allnow exit with an error when the web UI port is taken or the TLS certificate cannot be loaded. Before, the listener bound inside a goroutine, the error was only logged, and the process kept running without a web UI.--port/DAGU_PORTfor the web UI, and--coordinator.port,DAGU_COORDINATOR_PORTorDAGU_COORDINATOR_ENABLED=falsefor the coordinator in start-all.url=.First-launch examples
example-06-retry-on-failure: its first attempt fails and a step retry succeeds, which shows what an orchestrator adds over cron.example-03-schedulingno longer claims to be scheduled while its schedule is commented out.Web UI
/license#monitoring. The offer is dismissible and shown only to admins of Community servers whose license is not set by environment variables.patternattribute that browsers reject; the Start dialog showed "Parameters 0 fields".Packaging and README
hello.yamlin an empty folder (--dags .loads every YAML file in the folder), create the admin account, and a note for script-installer users whose service already runs on 8080.Why
A fresh install worked, but it showed nothing a cron job could not do, buried the free monitoring offer under Plan & features, and had sharp edges on the quick start path (silent port conflicts, a missing create button, stray YAML loaded as broken workflows).
