chore(tier): close the ignore/deploy drift, and stop justifying git-lfs by dead config

`deploy_file` excludes `*/Noctalia*` (noctalia's capital-N palette naming) but
`.gitignore` had only the lowercase classes, so a generated palette file could become
tracked-but-never-deployed — the fiction class #41 removed, reintroduced by the
ignore list falling out of step with the deployer. The patterns are one contract in
two files; both halves are now stated and the comment says so.

`natives/` (2.4 MB of tree-sitter grammars the harness unpacks into the repo root on
first use, measured on blankpad) sat unnamed in the root, one `git add -A` away from
being committed as configuration. It is runtime state by every clause of AGENTS.md's
doctrine, so it is ignored. The wallpaper re-fetch note pointed at
`https://wallhaven.cc/w/<id>`, which answers text/html — it now names the API
resolution the deploy page carries.

`git-lfs` was installed because `.gitattributes` routes image types through the LFS
filter — for wallpapers this week's diff untracked: `git lfs ls-files` is zero, so
those four rules match nothing. The manifest now states what the tool is actually for
(cloning LFS-backed upstreams such as Hugging Face model/dataset repos) and the file
records its own inert state. Deleting `.gitattributes` is a pruning call for a session
with Frank, not a cleanup an agent runs alone.

Verified with `git check-ignore -v` for both new rules.
