feat(shell): replace pager with ov, add logs browser, and auto-generate paru wrapper

- Set $PAGER to ov in config.fish (falls back to less); remove LESS=-R
- Rewrite less wrapper with full hierarchy: $PAGER → ov → less → more → cat
- Simplify view.fish fallback to delegate to the less wrapper
- Add logs function: fzf browser for scrollback and paru logs, opens in $PAGER
- Add claude wrapper: auto-injects --remote-control unless already present
- Add conf.d/paru-wrapper.fish: generates ~/.local/bin/paru on first run,
  versioned so future template changes auto-propagate on next shell start
- Sync README.md and requirements.md to document all of the above

conf.d/paru-wrapper.fish
