fix(zshrc): set ~/.local/bin on PATH before mise activate

[vaintrub]

Bug

command -v mise && eval "$(mise activate zsh)" ran ahead of export PATH="$PATH:$HOME/.local/bin". On Linux where mise is curl-pipe-installed to ~/.local/bin/mise, the command -v mise check fails because ~/.local/bin isn't on PATH at that point → mise activate silently skipped → tools not on PATH → fzf/zoxide integrations (which depend on mise activate) also don't fire.

Reproduction

Jetson (Ubuntu 22.04 aarch64, zsh login shell):

$ which delta
delta not found
$ mise where aqua:dandavison/delta
/home/vaintrub/.local/share/mise/installs/aqua-dandavison-delta/0.19.2
$ echo $PATH | tr ':' '\n' | grep -c mise/installs
0
$ eval "$(mise activate zsh)"
$ which delta
/home/vaintrub/.local/share/mise/installs/aqua-dandavison-delta/latest/.../delta

So mise is installed, paths exist, but activate never ran in zshrc. Manual eval fixes the session; next session breaks same way.

Why Mac was fine

Brew's .zprofile shellenv adds /opt/homebrew/bin (where brew-installed mise lives) to PATH before .zshrc fires → command -v mise succeeds → activate runs. Linux has no equivalent pre-zshrc PATH setup for ~/.local/bin (Ubuntu's ~/.profile adds it but only for bash; zsh would need ~/.zprofile which we don't deploy).

Downstream effect noticed first

chezmoi diff on jetson kept showing ~/.gitconfig wanting to remove the delta block — {{ if lookPath "delta" }} was evaluating false because chezmoi's rendering process inherited the unactivated shell's PATH. Looked like a chezmoi convergence issue at first; root cause is zshrc ordering.

Fix

Move the PATH extension block above the mise activate line:

PATH += ~/.local/bin, ~/go/bin
mise activate
fzf integration
zoxide init

Matches dependency direction. Mac unaffected (idempotent appends; activate already saw mise on PATH).

Test plan

• chezmoi apply on Mac workstation — no behavioural change, rtk init still wires correctly
• Order verified via grep -nE 'PATH|mise activate' dot_zshrc
• Jetson after merge: chezmoi update && chezmoi apply && exec zsh && which delta → mise install path; chezmoi diff → empty for gitconfig
