Mirror the OpenIPC/firmware nightly redesign (PRs #2111-#2129) to
builder. This commit is PR-Bld-A: the build.yml-side changes only.
Subsequent PRs add the manifest aggregator + retention sweep
(PR-Bld-B) and the build-one.yml commit input (PR-Bld-C).
Changes:
1. **Preflight SHA gate**. New `preflight` job reads `sha=` from the
rolling `nightly` release body. On schedule events it short-
circuits the matrix when HEAD matches the previously-published
SHA; PRs and workflow_dispatch always build. Mirrors firmware's
#2111.
2. **Three release tags per build**:
- `nightly-YYYYMMDD-<short>` (prerelease, content-addressable,
the unit of history — 90-day retention via PR-Bld-B's
cleanup.yml).
- `nightly` (rolling channel pointer; body carries sha/short/
built_at).
- `latest` (legacy alias, kept one cycle so existing sysupgrade
clients hitting the old hardcoded URL don't break).
3. **`BUILD_ID` / `BUILD_SHA` / `BUILD_PLATFORM` env** exported at
the job level from preflight outputs. firmware's rootfs_script.sh
(which builder.sh reuses via its clone of firmware) picks BUILD_ID
+ BUILD_SHA into /etc/os-release automatically. BUILD_PLATFORM is
set to the matrix entry (e.g. `gk7205v200_fpv_caddx-fly`) and is
forward-compatible with Phase 3 of the mirror plan (the firmware-
side rootfs_script.sh update that emits BUILD_PLATFORM as an
os-release field).
4. **Retry budget** around `bash builder.sh`. Matches firmware's
`30 60 120 300 600 1200` ladder, covering toolchain/CDN flakes
(#2115 + #2129 in firmware).
5. **Telegram caption** leads with `Build: <build_id>`; obsolete
`Tag: ${TAG_NAME}` line gone; workflow-level `env: TAG_NAME=
latest` removed.
No on-device firmware changes; builder cameras keep their existing
sysupgrade legacy URL until Phase 2 of the mirror (sysupgrade variant
routing) lands in OpenIPC/firmware.

The Build workflow's matrix-of-everything makes it slow and noisy to
test a single device profile. Mirrors the build-one workflow already
present in OpenIPC/firmware.
Takes a full platform name (e.g. hi3518ev200_lite_switcam-hs303-v2)
and runs only that build via builder.sh.

Rationale:
End users might not know exactly what hardware they have, they just want to find RubyFPV firmware options, so in the release page, in the list of released firmware packages, it makes sense to have all RubyFPV related configs in a single place in the list (so all start with the same RubyFPV prefix).
