Add ~/.local/bin to PATH for user-installed binaries

[davidkreps]

Summary

• Add ~/.local/bin to PATH in .zshrc so user-installed binaries (e.g. pip install --user, cargo install, claude) are available without manual PATH edits
• Remove stale claude alias that pointed to ~/.claude/local/claude (old install path), which was causing zsh: no such file or directory errors after Claude Code moved to ~/.local/bin

Test plan

• Open a new terminal and confirm claude resolves via which claude to ~/.local/bin/claude
• Confirm no "no such file or directory" error when running claude
• Run ./test.sh to verify no regressions

LGTM. This is a clean, minimal, and correct change. Here's a checklist against the conventions in CLAUDE.md:

Convention	Status	Notes
Portability (macOS + Linux)	✅	~/.local/bin is an XDG standard; used on both platforms
No hardcoded paths	✅	Uses $HOME
OS/tool guard	✅	[ -d "$HOME/.local/bin" ] silently skips if directory absent
Stdout-clean	✅	No echo or print side-effects
Trailing newline	✅	File ends with newline
install.sh consistency	✅	No new file — existing .zshrc symlink covers this
test.sh coverage	✅	Existing sourcing and hygiene tests cover this
Security	✅	No secrets; no external downloads
Idempotency	✅	PATH guard is a pure function of directory existence

One minor note: zsh/.zshrc ends with two blank lines (pre-existing, not introduced by this PR). The file hygiene test only checks for the presence of a trailing newline, so it passes — but you may want to trim the extra blank line at some point for tidiness.

The change follows the exact same pattern as the existing .npm-global/bin and VSCode PATH additions in the file. Positioning before .npm-global/bin is appropriate — user-local XDG binaries typically should take priority.

LGTM. Both commits are clean and correct. Here's the full checklist against CLAUDE.md conventions:

Convention	Status	Notes
Portability (macOS + Linux)	✅	~/.local/bin is XDG standard; works on both platforms
No hardcoded paths	✅	Uses $HOME throughout
OS/tool guard	✅	[ -d "$HOME/.local/bin" ] silently skips if directory absent; no OS guard needed since ~/.local/bin is cross-platform
Stdout-clean	✅	No echo or print side-effects added
Trailing newline	✅	File ends with a newline (test passes)
install.sh consistency	✅	No new file — existing .zshrc symlink covers this
test.sh coverage	✅	No new symlinks; existing sourcing and hygiene tests cover this
Security	✅	No secrets; no external downloads
Idempotency	✅	PATH guard is a pure function of directory existence

Commit 1 (ad07abf): Adds ~/.local/bin to PATH with a directory existence guard. Positioned before .npm-global/bin, giving user-local XDG binaries appropriate priority. Follows the exact same pattern as the existing npm and VSCode PATH additions.

Commit 2 (2f8b9e8): Removes the stale claude alias. The removed guard was [ -x "$HOME/.claude/local/claude" ] && alias claude="..." — a conditional alias that was safe but now obsolete since the binary moved to ~/.local/bin (which is on PATH). Clean removal, no replacement needed.

Pre-existing minor notes (not introduced by this PR, not blocking):

• zsh/.zshrc line 53: echo -ne '\e[5 q' runs unconditionally at shell init to set cursor shape. This emits an escape sequence to stdout on every shell start, which could technically interfere with scp/rsync (against the CLAUDE.md stdout rule). Worth a follow-up cleanup if that ever causes issues.
• Both zsh/.zshrc and zsh/aliases.zsh end with two blank lines. Hygiene test passes (trailing newline present), but one blank line would be tidier.
