Add ~/.local/bin to PATH, remove redundant claude alias

[davidkreps]

Summary

• Adds ~/.local/bin to PATH in .zshrc (guarded with a directory existence check)
• Removes the per-tool claude alias — it's now redundant since claude lives in ~/.local/bin

Test plan

• ./test.sh passes (36/36)
• claude resolves in a new shell session

Summary

This PR introduces two changes (commits 3cb5f02 and e075729):

1. zsh/.zshrc — adds ~/.local/bin to PATH, guarded by a directory existence check
2. zsh/aliases.zsh — removes the per-tool claude alias; also fixes a trailing space and extra blank line (the net diff against main after the merge commit)

Because main gained the .zshrc change through the PR #5 merge, the net diff is just the aliases.zsh whitespace cleanup — but the full intent of the PR is clear from the individual commits.

CLAUDE.md Checklist

Convention	Status
Uses $HOME (not hardcoded paths)	✅
No credentials / secrets committed	✅
Tool guard: PATH entry guarded with [ -d "$HOME/.local/bin" ]	✅
No stdout during shell init	✅
Trailing newline on aliases.zsh	✅ (one trailing newline, no extra blank line)
Works on macOS and Linux	✅
install.sh / test.sh consistency	✅ (no new symlinks — PATH is set in .zshrc)

Findings

zsh/.zshrc — PATH addition (3cb5f02)

# User-local binaries (XDG standard, e.g. pip --user, cargo, claude)
[ -d "$HOME/.local/bin" ] && export PATH="$HOME/.local/bin:$PATH"

• Guard is correct — only prepends when the directory exists.
• $HOME used throughout — portable. ✅
• Prepends to PATH, giving user binaries priority over system ones. This is the conventional behavior and matches how ~/.cargo/bin, ~/.npm-global/bin etc. are handled elsewhere in the file. ✅

Minor note (non-blocking): Sourcing .zshrc multiple times in the same session will add ~/.local/bin to PATH repeatedly. This is a very common pattern and harmless in practice — zsh deduplicates paths with typeset -U path if configured, and the duplicate is invisible to users. No change needed.

zsh/aliases.zsh — claude alias removal (3cb5f02)

# Removed:
[ -x "$HOME/.claude/local/claude" ] && alias claude="$HOME/.claude/local/claude"

Removing this is correct now that ~/.local/bin is on PATH. The old path (~/.claude/local/claude) is where Claude CLI used to install; the current standard location is ~/.local/bin/claude. Dropping the alias in favour of the PATH entry is cleaner and handles future updates automatically. ✅

zsh/aliases.zsh — trailing whitespace cleanup (e075729)

Removes a trailing space from the nowdate alias and the extra blank line. Aligns with the CLAUDE.md rule that all files must end with exactly one trailing newline. ✅

Verdict

LGTM. The changes are clean, well-guarded, and consistent with the repo's conventions. No blocking issues.
