What does this implement/fix?

This PR introduces several new components and features to ESPHome:

  1. Template Climate Component - A new climate component that allows users to create custom climate devices through templates, similar to existing template sensor/switch/cover components. Includes support for custom presets, fan modes, and swing modes.

  2. Snapshot Component - A host-only component for capturing display output to image files, useful for testing and debugging display-based configurations.

  3. CDC ACM UART Bridge - Enables UART communication over USB CDC ACM on ESP32 variants (P4, S2, S3) that support it, with proper task management and ring buffer handling.

  4. ESP-NOW over esp-hosted - A shim implementation allowing ESP-NOW to work on radio-less hosts (like ESP32-P4) by forwarding calls to a co-processor via CustomRpc.

  5. E-paper UC8179 Controller Support - Added support for UC8179-based e-paper displays (e.g., Waveshare 7.5" v2).

  6. Additional Components:

    • D01 sensor component
    • DS1603L sensor component
    • Various bug fixes and improvements to existing components

Types of changes

  • New feature (non-breaking change which adds functionality)
  • New developer-facing feature (adds functionality for component developers)
  • Code quality improvements to existing code

Test Environment

  • ESP32
  • ESP32 IDF

Checklist:

  • The code change is tested and works locally.
  • Code follows ESPHome conventions and style guidelines.

[core] Isolate contextvars per task in the coroutine runner
bbc8ed3 
FakeEventLoop stepped every task's generator with a bare next(), so a
contextvar set inside one to_code() job could leak into an unrelated job
the scheduler interleaves it with. Give each task its own copied Context
and step it through Context.run(), the same isolation real asyncio.Task
provides internally, without touching the priority-based scheduling that
keeps generated C++ output deterministic.
