ci: stage observer+ flasher channel workflow (disabled)

Second-channel pipeline for mqtt-observer-plus, mirroring
build-observer-firmwares.yml with full channel isolation:
- rolling tag observer-mqtt-plus-latest (never shared: per-tag asset pruning
  would cross-delete on a shared tag)
- FIRMWARE_VERSION v1.16.0-plus, separate build counter
- OTA_MANIFEST_BASE overridden to /v-plus at build time so device pull-OTA
  can never hop a plus node back onto the stable channel (env build flags
  append after ini flags, so the override wins — verified in the binary)

Not enabled: workflow_dispatch only (push trigger staged in comments), and
the flasher-repo sync is gated behind SYNC_FLASHER=false with a fail-closed
guard so a premature enable cannot clobber the stable config.json. The
header documents the flasher-side prerequisites (channel-aware
update-firmware.py, SPA channel picker, v-plus manifests, plus changelog).
Manual dispatch already works for publishing hand-flashable test builds to
the release page.

name: Build MQTT Observer+ Firmwares (keymind channel)
# ============================================================================
# STATUS: STAGED BUT NOT ENABLED — manual dispatch only.
#
# This is the experimental "plus" channel (mqtt-observer-plus = flex +
# mcarper/keymindCascade). It mirrors build-observer-firmwares.yml with the
# channel isolated end-to-end:
# - rolling release tag: observer-mqtt-plus-latest (NEVER share the
# stable tag: each workflow prunes old assets within its tag by build
# hash, so a shared tag would have the channels deleting each other's
# binaries)
# - firmware version: v1.16.0-plus (filenames + embedded `ver`)
# - device pull-OTA: OTA_MANIFEST_BASE overridden to .../v-plus so
# `ota update` on a plus node can never "update" it back onto the stable
# channel (the per-env platformio.ini bakes .../v; the env-injected flag
# below wins because PLATFORMIO_BUILD_FLAGS append after ini flags —
# verified by building and checking the embedded URL string)
#
# TO ENABLE THE CHANNEL:
# 1. Uncomment the `push:` trigger below.
# 2. Flip SYNC_FLASHER to "true" — but FIRST the flasher repo
# (agessaman/flasher.meshcore.io) needs channel support; until it does,
# the sync step below fails closed on purpose so the stable config.json
# cannot be clobbered. Flasher-side prerequisites:
# - update-firmware.py: a --channel/--config argument writing a
# plus-specific config (e.g. config-plus.json), not config.json
# - SPA: a channel picker (Observer / Observer+ experimental)
# - gen-slim-manifests.py output dir flasher/v-plus (arg already
# parameterized; wired below)
# - a plus changelog target (CHANGELOG-plus.md) — the stable
# CHANGELOG.md tracks the flex branch only
#
# Until SYNC_FLASHER is enabled, the per-base build counter has no writer, so
# every manual dispatch publishes as build .1 — fine for hand-flashed testing
# off the release page.
