cproudlock 2e42972f44 Map the image channels to how this repo ships, and disarm auto-publish
The channel work assumed the branch model it was written against: upstream,
main is a release branch and dev-be is the trunk. Neither holds here. main IS
our trunk - 212 commits past v0.11.3 - and a release is a tag (ADR-007). dev-be
does not exist at all, so the edge half would never have fired and the launchers
would have cloned a missing branch.

Taken literally it would have published our unreleased trunk to every site as
:stable, which is the opposite of what the word promises to someone who has no
way to check.

Remapped throughout:

  tag v*  -> :stable   the thing that was actually released
  main    -> :edge     the trunk, DEV badge lit

publish-images.yml keys the channel on github.ref_type = tag rather than on a
branch name, so the mapping cannot silently drift back. Start-ShopDBDev.ps1,
dev-bootstrap.ps1 and build-channel-installer.ps1 resolve stable to the newest
v* tag via git ls-remote --sort=-v:refname, warning and falling back to main if
a repo has no tags yet. DEV-BUILD-TEST.md follows.

The push: trigger is commented out. Automatic publishing waits on someone
confirming the GHCR package exists under this owner and deciding who may pull
it; workflow_dispatch works meanwhile. Turning it on is one uncomment.

All three scripts parse clean under pwsh, and the tag-selection expression was
run against this repo rather than eyeballed. Per the standing rule, the runtime
paths still want a pass in the win11 VM before anyone leans on them.

.SYNOPSIS
Save-and-run launcher for a ShopDB dev workstation (stable or edge).
.DESCRIPTION
Download this one file and run it. It clones (or updates) the repo at the
channel branch into a local path, then hands off to scripts/dev-bootstrap.ps1
for the real dependency-check / build / up work.
ge-aero/shopdb-flask is a PRIVATE repo, but this needs no token pasting: the
clone uses a plain https URL and Git Credential Manager supplies your stored
GitHub credential automatically - the same way `git clone` works in the wiki
DEVELOPMENT-SETUP procedure. If you have ever cloned this repo or signed in to
GitHub in Visual Studio / VS Code on this box, GCM already has what it needs.
This is a downloaded FILE, not a web `iex` one-liner, precisely because a
private repo cannot be fetched anonymously from raw.githubusercontent.com. A
saved script sidesteps that entirely - only the git operations need auth, and
GCM handles those.
.PARAMETER Channel
'stable' (the newest release tag) or 'edge' (main, the trunk). Defaults to 'stable'.
.PARAMETER TargetDir
Where to clone. Defaults to %USERPROFILE%\shopdb-dev, a separate working copy
from any repo you already have open.
.EXAMPLE
# Bleeding edge:
powershell -ExecutionPolicy Bypass -File .\Start-ShopDBDev.ps1 -Channel edge
.EXAMPLE
# Stable:
powershell -ExecutionPolicy Bypass -File .\Start-ShopDBDev.ps1 -Channel stable
.NOTES
ASCII only, no emoji or smart punctuation, per repo style. PowerShell 5.1+.
Needs Git (with Credential Manager, the Git-for-Windows default);
dev-bootstrap.ps1 offers to winget-install anything else that is missing.
