CodeWhale (https://github.com/Hmbown/CodeWhale) is the actively-maintained
successor to DeepSeek TUI — same author, renamed project. Added as a dual
entry alongside the existing "deepseek-tui" catalog entry (rather than a
hard rename) so users who still run the old DeepSeek TUI binary keep a
working dashboard card, while new users are steered to "codewhale".
New /api/cli-tools/codewhale-settings route writes the primary
~/.codewhale/config.toml and keeps an existing legacy
~/.deepseek/config.toml in sync (read fallback + best-effort write sync),
mirroring deepseek-tui-settings/route.ts. CLI_TOOLS and cliRuntime catalogs
updated; catalog cardinality tests/constants bumped accordingly (18→19
visible code tools, 28→29 total).
