J. Nick Koston fa055b9e49 [core] Lazy-load zeroconf/writer/yaml_util in __main__

Every \`esphome\` CLI invocation pays the cost of whatever \`esphome/__main__.py\`
imports at module scope before the requested command even runs. This
moves three heavy imports into the functions that actually use them:

- \`esphome.zeroconf\` (discover_mdns_devices): only needed for the
  name_add_mac_suffix OTA discovery path.
- \`esphome.writer\`: only needed by compile/clean paths.
- \`esphome.yaml_util\`: only needed by codegen, config dump, and rename.

Local measurement drops from ~75ms to ~47ms (-37%) for a cold
\`python -c 'import esphome.__main__'\`. The zeroconf chain alone accounts
for most of the gain — the case that motivated the CI budget check.

Also adds a module-level note explaining the intent so future PRs don't
innocently promote these back to the top.

Retargets four test patches from \`esphome.__main__.discover_mdns_devices\`
to \`esphome.zeroconf.discover_mdns_devices\` now that the symbol is only
bound inside the function that calls it.

Tests for ESPHome

This directory contains some tests for ESPHome. At the moment, all the tests only work by simply executing esphome over some YAML files that are made to test whether the yaml gets converted to the proper C++ code.

Of course this is all just very high-level and things like unit tests would be much better. So if you have time and know how to set up a unit testing framework for python, please do give it a try.

When adding entries in test_.yaml files we usually need only one file updated, unless conflicting code is generated for different configurations, e.g. wifi and ethernet cannot be tested on the same device.

Current test_.yaml file contents.

Test name	Platform	Network	BLE
test1.yaml	ESP32	wifi	None
test2.yaml	ESP32	ethernet	esp32_ble_tracker
test3.yaml	ESP8266	wifi	N/A
test4.yaml	ESP32	ethernet	None
test5.yaml	ESP32	wifi	ble_server
test6.yaml	RP2040	wifi	N/A
test7.yaml	ESP32-C3	wifi	N/A
test8.yaml	ESP32-S3	wifi	None
test10.yaml	ESP32	wifi	None
