Peace Room ask (2026-07-09): during P0 triage the team needs to spot
which prod deploys skipped the RT sign-off flow, since hotfixes see
less scrutiny and are more likely culprits.

Adds a classify-deploy-type step ahead of send-notification. The signal
is already in the image_tag shape — RT deploys tag vX.Y.Z-rc.YYYY-MM-DD.N,
everything else (plain semver main deploys, feature-branch tags,
ad-hoc) is treated as hotfix. No new inputs, no per-caller changes.

Message prefix change:
  before: *webstore deployed by pdodgen*
  RT:     🚂 *RT* · *webstore deployed by pdodgen*
  Hotfix: ⚡ *Hotfix* · *webstore deployed by pdodgen*

Fallback `text` field (used for notifications + screen readers) gets
the plain-text badge form ("🚂 RT · webstore deployed").

Prod-only by structural design: callers only invoke this workflow from
prod deploy paths (deploy-eks.yaml → slack-notification), so every
message emitted here is a prod message. No env gate needed.

Jellyfish parser (per previous dual-tag-format work) anchors on the
version line and repo name, not the header prefix — the added badge
does not affect its regex.
