fix(shell): clean up rcfiles and remove redundancies

- Remove deprecated GREP_OPTIONS (handled via alias)
- Quote $ZSH_COMPDUMP to prevent word splitting
- Remove duplicate vim alias (nvim alias takes precedence)
- Consolidate completion path to ZSH_CUSTOM_COMPLETION_PATH
- Simplify PATH setup in rcfiles, centralize in exports
- Move LM Studio PATH from rcfiles to exports
- Add clarifying comments for macOS-specific ssh-add
