Subject: refactor(term): finish ghostel retirement (phase 5)

Remove the dead ghostel app from theme-studio: the GHOSTEL_FACES/SEED data, the registry row, the renderGhostelPreview previewer, and the package_seed test, then regenerate the tool. ansi-color stays since eat inherits it. Rename testutil-ghostel-buffers to testutil-terminal-buffers and drop make-fake-ghostel-buffer; the toggle-filter test now uses the eat fixture, since agents are eat. Fix the comments that still called the agent buffers ghostel (they're eat now) in eat-config and the ai-term and auto-dim test docstrings. I also package-deleted the unused ghostel ELPA package. Full suite green; the remaining ghostel mentions are accurate migration history.
