Merge 10-rbenv-path (disabled, PATH-only) into 20-rbenv (active, init),
so both path_prepend and rbenv init live under one existence guard.

Extracted history, shell options, dircolors, rbenv, ~/.local/bin PATH,
and Maestro PATH from ~/.bashrc into dedicated .bash.d/ files, reducing
.bashrc from 126 lines to a minimal 23-line loader.
New files:
- 10-local-path: ~/.local/bin via path_prepend
- 10-maestro-path: ~/.maestro/bin via path_append
- 20-rbenv: rbenv init with existence guard
- 30-shell-options: history, checkwinsize, dircolors
