fix(fish): add ~/.railway/bin to PATH

[shunkakinoki]

Summary by cubic

Add ~/.railway/bin to PATH in fish Home Manager config so the Railway CLI is available in all shells.
Sets it early in PATH and adds fish_add_path on both Linux and macOS to avoid “command not found” after install.

^{Written for commit 52874aa. Summary will update on new commits.}

PR Summary

Adds ~/.railway/bin to the fish shell PATH so the Railway CLI (installed via railway.com/install.sh to ~/.railway/bin/railway) is discoverable from fish sessions. The change is applied in all three fish init blocks to cover non-interactive, login, and interactive shells uniformly.

• home-manager/programs/fish/default.nix: prepend $HOME/.railway/bin in shellInit's set -gx PATH line.
• home-manager/programs/fish/default.nix: add fish_add_path -p -m ~/.railway/bin in loginShellInit at a low-priority slot.
• home-manager/programs/fish/default.nix: mirror the same fish_add_path entry in interactiveShellInit for parity.

Issues

1 potential issue found:

• zsh (home-manager/programs/zsh/default.nix) and bash (home-manager/programs/bash/bash_env.sh, default.nix) PATH blocks don't include ~/.railway/bin, so railway will be missing there; primary shell is fish so this is a parity nit, not a bug. → Autofix

📝 Walkthrough

Summary by CodeRabbit

• New Features
  • Fish shell sessions now include ~/.railway/bin in the PATH, making Railway commands available more consistently.
  • PATH setup is applied for both login and interactive Fish shells, improving access across different terminal start modes.

Walkthrough

The Fish shell configuration adds ~/.railway/bin to PATH: prepended in the shellInit PATH export, and added via fish_add_path -p -m in both loginShellInit and interactiveShellInit hooks.

Poem

A rabbit hops with railway cheer,
New bin path now sitting near,
Fish shell whispers, "PATH's complete,"
Login or interactive, both a treat,
Hop hop hooray, the tracks are set! 🐰🚂

Code Review

This pull request adds the ~/.railway/bin directory to the PATH configuration in home-manager/programs/fish/default.nix across multiple blocks to ensure Railway binaries are available in the Fish shell environment. I have no feedback to provide.

Parity nit: ~/.railway/bin is only being added to fish. The zsh (home-manager/programs/zsh/default.nix:35 and the initContent PATH stack) and bash (home-manager/programs/bash/bash_env.sh, home-manager/programs/bash/default.nix) configs still don't include it, so invoking railway from those shells will fail. Since hosts/nixos/default.nix:55 sets shell = pkgs.fish; this is likely intentional scope — flagging in case you want the other shells kept in sync.
