fix(esp32c6): add missing build.variant to esp32-c6-devkitc-1

[zackees]

Summary

• esp32-c6-devkitc-1.json was the only ESP32 board (out of 50) missing build.variant, causing variant to default to the board ID and look for nonexistent variants/esp32-c6-devkitc-1/ instead of variants/esp32c6/
• Added "variant": "esp32c6" to the board JSON
• Added regression tests for both the direct board ID and the esp32c6 alias path

Test plan

• test_esp32c6_devkitc1_has_variant — RED before fix, GREEN after
• test_esp32c6_alias_has_variant — confirms alias path works
• Full fbuild-config suite (102 tests) passes
• CI passes on this PR

Fixes #46
Cross-ref: FastLED/FastLED#2259
