v0.10.1

• Breaking: project slugs are now validated strictly at startup: 1-48 characters
  from a-z, 0-9 and -, with no leading, trailing or repeated -. The same rule
  covers Alertmanager project label keys. Every invalid or duplicate slug is reported
  by name in one error, so fix the configuration file before upgrading.
• Projects are addressed by slug in web URLs and the API (/projects/{slug}). The old
  6-character short id still works and the UI redirects it to the slug URL. Email,
  webhook and Alertmanager notification links use the slug.
• Teams get a short id used in /teams/{short_id} URLs. The team API accepts the short
  id or the UUID, and the UI redirects UUID URLs to the short form.
• Alertmanager: per-project severity and source links, global and per-project refresh
  intervals, and alert names selected by effective severity. Severity defaults to
  critical.
• Alertmanager defaults and alert names can be managed through environment variables or
  the admin UI. Test alerts can be sent from the service settings and from a monitored
  project's settings.
• All Alertmanager delivery failures are now reported to Sentry.
• Added an Alertmanager guide with complete configuration and VMRule examples.
• Project admins can regenerate the project DSN from the SDK Setup page, behind a
  confirmation dialog.
• Projects removed from the configuration are shown as disabled: a Disabled pill on the
  project page, and a badge with muted styling at the bottom of the dashboard.
• Settings managed by configuration are marked with a notice that stays highlighted
  while you hover nested controls. Team pages show it as a pill under the team name.
• UI polish: text selection is disabled except in fields, code and event data, and
  special characters no longer end up in avatar initials.
• Performance: notifications are delivered in a background task (up to eight at a time),
  so SDK requests never wait on SMTP, webhooks or Alertmanager. Event ingestion does less
  database work and the issue list uses its index.
• Ingest bodies are capped at 20 MiB after decompression (413 above the limit).
• Helm chart: the deployment strategy is configurable and values.yaml lists the
  environment variables the application reads.
