Migration notice for binary filenames

[2024 Dec 20] Binaries have been renamed w/ a whisper- prefix. main is now whisper-cli, server is whisper-server, etc (https://github.com/ggerganov/whisper.cpp/pull/2648)

This migration was important, but it is a breaking change that may not always be immediately obvious to users.

Please update all scripts and workflows to use the new binary names.

Old Filename	New Filename
main	whisper-cli
bench	whisper-bench
stream	whisper-stream
command	whisper-command
server	whisper-server
talk-llama	whisper-talk-llama
