Walkthrough

This PR updates Integrations/ESPHome/Core.yaml: bumps the firmware substitution version, enforces PSRAM presence at boot via ignore_not_found: false, replaces the shared media resampler with separate announcement/media resamplers, shifts task stack placement to internal RAM, and adjusts media_source buffer sizes and decode memory settings.

Changes

ESPHome Core Config Update

Layer / File(s)	Summary
Firmware version and PSRAM enforcement Integrations/ESPHome/Core.yaml	Firmware version substitution bumped from 26.7.7.2 to 26.7.8.1; psram.ignore_not_found set to false, causing boot failure if PSRAM is absent.
Audio resampler and memory reconfiguration Integrations/ESPHome/Core.yaml	Introduces separate announcement_resampling_speaker and media_resampling_speaker resampler components, sets sendspin_hub.task_stack_in_psram to false, removes explicit decode_memory: internal on sendspin source, increases audio_http buffer sizes, and rewires the announcement pipeline's speaker to announcement_resampling_speaker.

Poem

A rabbit hops through YAML fields at night,
Splitting streams of sound just right—
Announcements here, media there,
PSRAM now demands its share.
Buffers grow, the stacks stay grounded,
Firmware bumped, and boot resounded! 🐇🎧
