feat(profiles): add jwtf/phok-dev helpers, fix zoxide/zinit PATH ordering

- Add jwtf to cd into the repo root (with pass-through command support,
  same pattern as phok)
- Add phok-dev alias forcing software H.264/H.265 decode and disabling
  DMA-BUF rendering, working around this laptop's Intel iHD VA-API driver
  corrupting hardware-decoded frames during Phokus dev builds
- Move nvm/bun/PATH setup above zinit init so PATH is fully resolved
  before zoxide's hook and zinit's scheduler register - fixes intermittent
  "command not found: zoxide/sleep/true" errors
- Drop zinit wait lucid turbo mode; its async scheduler was the source
  of the above errors
- Rename up()'s local path var to target to avoid shadowing zsh's
  special path array
