feat: surface cron windows in webapp, cli, sdk

[carderne]

Summary

Adds execution-window product surfaces for both declarative and imperative schedules.

• Declarative schedules can set window through schedules.task(), with support for whole-minute, hour, and percentage values.
• Imperative schedules can create, update, clear, and inspect windows through the API and dashboard.
• Schedule API responses preserve nextRun as the nominal CRON time and expose nextRunEffectiveAt as the stable assigned time.
• The dashboard displays configured windows alongside assigned upcoming-run times.
• Deploy output summarizes declarative schedules and suggests adding a wider window when the default 60-second placement range is used.

Design

Window validation remains authoritative on the server and ensures each window is compatible with the schedule cadence. Omitting a window uses the default 60-second range, while explicit zero-duration windows remain supported.

Deployment summaries are derived from the deployment's stored task metadata, so they reflect the declarations associated with that deployment.

Walkthrough

The change adds optional duration or percentage windows to declarative schedules. Scheduling utilities calculate nominal CRON times and effective assigned times. Presenters and APIs return both timestamps and window metadata. Dashboard views and forms display and edit windows. Deployment responses and CLI output include declarative schedule details. Tests cover SDK serialization, timing calculations, API lifecycle behavior, and deployment formatting.

Observability map

As of 6a73a1a.

Nothing in this pull request moves the report any more. The findings an earlier push reported are gone.

The score and findings here are report-only and never gate the merge. Separately, a required test suite keeps this tool's symbol and route lists in sync with the code they name, and can fail a pull request that renames or removes a symbol they reference, or that adds the first route with a segment they anticipate. Each failure names the list to edit. The rules and their reasons: internal-packages/observability-map/README.md.
