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: [email protected] → 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.

@copilot Looks like build failed. Also are you sure you rebased? We might as well make this PR target master branch.

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 [email protected] to pioarduino/platform-espressif32#55.03.35.

This change is necessary because the official [email protected] 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.
