install.sh adds sh-style PATH manipulation to fish config

[SavageMessiah]

I used the one line install on macos and it broke my fish config because it added export PATH="/Users/kenallen/.local/bin:$PATH" to the end which naturally does not work. ~/.local/bin was already on my path as well so it wasn't necessary to change anything anway. Trivial to fix on my end but that's something you can improve about the install script.

Thanks for flagging this — you were right, the install script wrote POSIX syntax into every shell rc. cbm_ensure_path appended export PATH="~/.local/bin:$PATH" unconditionally, which is a syntax error in fish and broke your config.fish.

Fixed in commit 30dfa95: when the target is a fish config (*.fish), the installer now emits the fish-native fish_add_path ~/.local/bin instead — idempotent, and only prepends if the entry isn't already on PATH (so it also avoids the unnecessary edit you noted when the dir is already present). POSIX shells (bash/zsh) are unchanged. Regression test cli_ensure_path_fish_syntax_issue319 added. Ships in the next release — thanks!
