Upgrade ESP32 platform to v3.3.5 stable release

[Copilot]

• Rebase onto master branch
• Update platform to pioarduino fork v3.3.5 (tag 55.03.35)
• Migrate code to Arduino-ESP32 3.x APIs
• Test build in CI (requires GH_TOKEN for private dependencies)

Changes:

1. Platform update: espressif32@6.12.0 → pioarduino/platform-espressif32#55.03.35 (Arduino 3.3.5)
2. API migrations for Arduino-ESP32 3.x:
   • Buzzer: ledcSetup()/ledcAttachPin() → ledcAttach(), ledcChangeFrequency() → ledcWriteTone()
   • Vibration: ledcSetup()/ledcAttachPin() → ledcAttach(), all channel references → pin references
   • Watchdog: old esp_task_wdt_init() → new esp_task_wdt_config_t struct

Now based on master (cfd1d2f) with single commit containing both platform and code updates.

You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this

If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -c with the switch command. Example:

git switch -c

Heres part of the build failure ...

Yes, I've rebased onto master (cfd1d2f). The branch now has a single clean commit on top of master that updates the platform from espressif32@6.12.0 to pioarduino/platform-espressif32#55.03.35.

This change is necessary because the official espressif32@6.12.0 only supports Arduino-ESP32 v2.0.17, but the codebase uses v3.x APIs (ledcAttach, esp_task_wdt_config_t, etc.). The pioarduino fork provides Arduino-ESP32 v3.3.5 support.

The build log excerpt you showed appears to be cut off during platform installation. I'll push the rebased branch now - commit 7b59e24.
