fix: resolve/install the bundled CLI as programa, not cmux (Phase 6f functional)

The CLI product is PRODUCT_NAME=programa and is bundled at Contents/Resources/bin/programa,
but the app still looked for bin/cmux and installed /usr/local/bin/cmux — a pre-existing
mismatch (main is mid-rebrand) that left the 'Install CLI' + CLI resolution broken. Point
them at bin/programa and /usr/local/bin/programa. Also fix the remaining 'programa welcome'
terminal command send, the menu-bar title/tooltip, and brand fallbacks (window title, app
name for notifications) cmux → Programa. Socket contract already agrees (shared last-socket-path
hint). Builds green.
