refactor(shell): reorganize shell config for proper separation

Restructure shell configuration to follow standard conventions:
- .profile: Environment variables only (POSIX compatible)
- .bash_profile: NEW - sources .profile and .bashrc for login shells
- .bashrc: Bash-specific settings, sources .bashrc.d/
- .zshrc: Zsh-specific settings, sources .zshrc.d/

New modular directories:
- .bashrc.d/: aliases, emacs, fzf, git, media, utilities
- .zshrc.d/: same as bashrc.d plus arch-downgrade (zsh-only)
- .profile.d/: reduced to env-only files (display, framework, auto-tmux)

Fixes:
- Remove duplicate .profile sourcing in .bashrc
- Remove broken XDG_CURRENT_DESKTOP=GNOME line from display.sh
- Move aliases/functions from .profile to appropriate .d/ directories
- Shell-specific init (zoxide, fzf) now in .bashrc/.zshrc directly
- FreeBSD bindkey fix now in .zshrc directly

Also adds CLAUDE.md session context file.
