Adds a shared/modules symlink mechanism for optional plugin modules
ModuleOrchestrator already discovers SlpModularCms.Modules.*.dll from disk at
startup via reflection, so this needed no code change — only a persistent
location (mirroring shared/wwwroot-web) that survives release swaps, and a
deploy-scp.yaml step to symlink its contents into each new release before
restart.

# Reusable deploy workflow, invoked by continuous_integration.yaml (U5) for both the automatic
# test deploy and the opt-in production deploy. One workflow, one input contract, so a second
# transport (e.g. FTPS for a future shared-hosting target) can be added later as an alternative
# without restructuring this workflow or its callers (FR-02, D-02, NFR-09).

# The customer's public website (wwwroot/web) must survive every CMS deploy (FR-08, ASM-01).
# It lives outside the swapped release directory in a persistent shared/ folder, and is
# symlinked into each new release. mkdir -p is idempotent, so this is also correct on the very
# first-ever deploy, before any website workspace has published anything there (U1 already
# tolerates a missing wwwroot/web at startup). The publish output's own wwwroot/web (empty, or
# containing only the placeholder page) is removed before the symlink is created, so it never
# shadows the persistent content. `mkdir -p $RELEASE_DIR/wwwroot` guards against `ln -s` failing
# with "No such file or directory": dotnet publish only emits a wwwroot/ folder at all when the
# source project has one with actual content, so a release built before any frontend content
# exists can land with no wwwroot/ directory whatsoever, not merely an empty wwwroot/web/.

# shared/modules lives entirely under gitea-workflow's own tree (unlike wwwroot-web, which
# reaches into webadmin's). ModuleOrchestrator.DiscoverModules() already scans its own base
# directory on disk for matching assemblies at startup (SlpModularCms.Core/Hosting/
# ModuleOrchestrator.cs) and loads whatever it finds via reflection — no code change needed,
# only somewhere for the DLL to still be after the next deploy replaces releases/{timestamp}.
# `ls ... 2>/dev/null` piped to a `while read` (rather than a bare glob loop) keeps this
# POSIX-sh safe and correct when shared/modules is empty, which is the common case today.
