Per-SoC family counts

Platform	Old	New	Δ
bk72xx	96	96	+0
esp32	166	168	+2
esp8266	167	167	+0
rtl87xx	5	5	+0

Smoke tests: ✅ pass script/check_device_catalog.py and script/check_bluetooth_proxy_catalog.py — known well-formed upstreams still extract with the expected board, variant, and component shape.

Review checklist:

• Skim the Added / Removed lists above for anything unexpected. A removed device usually means the upstream page was deleted or renamed.
• Hand-curated boards (no source: block) are never touched — each sync only owns manifests carrying its own source.type (esphome-devices or bluetooth-proxies).
• If the diff looks weird, run script/sync_esphome_devices.py --device <name> locally to inspect a single device.
• Merge to ship the new device catalog.
