Correct docs and the sort label ahead of the next release

A docs audit and QA pass over main (0.4.0 plus #37-#40) turned up a handful
of places where the docs and the UI had drifted apart:

- CHANGELOG: link issue #35 alongside PR #38 on the TTL-outlier entry, to
  match how the sibling entries cite their issue. Amend the 80-column entry
  to cover the Time -> Ping header rename and the matching `--once` column
  widths and right-aligned TTL, and the error-badge entry to mention that
  the badge also covers the "not a domain name" label. Drop a stray blank
  line between two bullets in the released 0.4.0 section.
- README: bump the Nix pin example to v0.4.0, the newest tag that exists.
- app.rs: `SortMode::label` still said "time" for the latency sort, so the
  footer disagreed with the column #40 renamed to Ping. Say "ping", and
  update the README key-binding row to match. No changelog entry of its
  own: the label ships unreleased, covered by the amended #40 entry.
- main.rs: document the `"<fg> on <bg>"` theme form in the long --help,
  which #40 added but never wrote down.
- AGENTS.md: the module map was missing theme.rs, globe.rs and
  world_data.rs, still described sites.rs as id.server-only (NSID leads
  since #39) and config.rs as resolvers-only (it owns theme/ecs/view too),
  and app.rs now owns TableLayout.

Verified: cargo fmt --check, clippy -D warnings and 120 tests pass;
`--once` prints its table; --help shows the new theme line; and driving the
real binary through a PTY shows the footer read "sort: ping" after cycling
Ctrl+S twice to the latency mode.
