mirror: add eza, fzf, tree packages (linux amd64 + aarch64)

- eza 0.23.5, fzf 0.74.3, tree 2.3.2 .pdm, built from upstream binaries
  (eza/fzf GitHub releases, tree from Debian pool), data at bin/<tool>.
- registry entries fzf.json/eza.json/tree.json with amd64+aarch64 variants.
- packages.json aggregate updated.
- verified end-to-end against a local mirror: 'pmm install fzf' selects the
  linux/amd64 variant, installs, and the binary runs.
