JonKazama-Hellion e5ac4faf7b ci(forge): auto-announce changelog to hellion forge on tag push
New workflow: when a vX.Y.Z tag is pushed (or workflow_dispatch
runs with a tag input), reads .github/forge-posts/<tag>.md for the
DE bullet body plus frontmatter (subtitle, versionsnatur), pulls the
matching English block from HellionChat.yaml, builds the Discord
webhook embed and posts it to the Hellion Forge #changelog channel.

Decoupled from release.yml — a fail here doesn't block the release,
and a fail there doesn't block the announce. Hard caps at 5500 chars
total (title + description + footer); major releases that exceed
that get a clear fail message and stay manual.

Tag is read via env: TAG_NAME and validated against ^v\d+\.\d+\.\d+$
before any string interpolation; frontmatter is regex-parsed with
explicit length caps (subtitle 60, versionsnatur 40). Curl posts the
payload via stdin so the secret never appears in process args.
Single retry on transient 5xx after 30s, hard fail on 4xx.

name: Forge Announce
# Triggered when a vX.Y.Z tag is pushed. Reads .github/forge-posts/<tag>.md
# (Frontmatter + DE bullet body) and the matching English block from
# HellionChat/HellionChat.yaml, builds a Discord-Webhook embed and posts
# it to the Hellion Forge #changelog channel.
#
# Decoupled from release.yml: a fail here does not block the GitHub
# release, and a fail there does not block the announce. Spec lives in
# the Vault under "Hellion Chat Forge-Auto-Announce Spec".
#
# Security: the only user-controlled inputs that enter run-steps are the
# tag name and the frontmatter values from a repo-internal markdown file.
# Tag name is read via env: (TAG_NAME, $env:TAG_NAME) and validated against
# ^v\d+\.\d+\.\d+$ before any string interpolation. Frontmatter values are
# parsed by regex with explicit length caps. No webhook event payload data
# (issue titles, PR bodies, commit messages, etc.) flows into run-steps.
