v0.7.0

Added

• Eight ports of established colorschemes ship with the reader:
  catppuccin-latte, catppuccin-mocha, dracula, gruvbox-dark, nord,
  solarized-dark, solarized-light and tokyo-night. --style <name>
  selects one, themes lists them, and the picker previews them like any
  other.

  They are TOML files in themes/, embedded with include_str! and parsed by
  the same loader a user theme goes through — the rule that a shipped theme
  must not be a privileged code path, now that there is more than one kind of
  shipped theme. A file of the same name in the user's theme directory still
  wins, so retuning one is a copy and an edit rather than a fork.

  Only Solarized has an exact counterpart among the seven syntax themes the
  highlighter carries; the rest are paired by eye. docs/THEMES.md has the
  schema, the seven names, and what a theme PR needs.

• <details> and <summary> are rendered instead of being printed as
  tags. The block becomes a quote titled by its summary, always open: a
  terminal page has no click, and hiding the body would lose content the
  author shipped.

  A blank line inside <details> ends the HTML block — CommonMark's rule, and
  the form GitHub requires for markdown to render inside — so the open tag and
  the body arrive separately and the body is not ours to wrap. In that case
  the summary stands alone as a strong paragraph rather than as a gutter bar
  around nothing, and the body follows as itself.

• Manifests for the AUR and nixpkgs, in packaging/aur/ and
  packaging/nix/. Two AUR packages, one building from source and one
  unpacking the release archive; a nixpkgs-style derivation written in the
  shape pkgs/by-name wants. Neither is published yet, and
  packaging/README.md says what each still needs.

• docs/demo.tape, a VHS script for the README's animated demo. It
  records the moving parts only — the contents pane tracking the scroll,
  folding, search narrowing as you type, the theme picker previewing. Not
  gated in CI: a GIF is a lossy re-encode, so a byte-comparison would be
  flaky rather than protective.

Changed

• $E = mc^2$ reads as a code span rather than as a formula wearing its
  dollar signs. ENABLE_MATH had never been in the parser's option set,
  while the handler for the events it produces had been sitting there since
  the beginning — so every $ in a document reached the page literally,
  through code that could not run. TeX is not typeset; there is no glyph
  budget for that in a cell grid, and code styling marks the span as notation
  without pretending otherwise.

• themes measures its own name column rather than padding to a fixed
  twelve, which the first bundled palette overran.

Fixed

• An overlay panel no longer leaves an unpainted cell beside it when its
  edge cuts a double-width glyph in half. The panel paints over the glyph's
  first cell; the second is one column outside it and belongs to nobody, so it
  stayed as the terminal left it — a one-cell hole showing the shell's
  background, hard against the border.

  Latent since the overlays were written, and reachable only when a panel's
  width put its edge on a wide glyph. Shipping a few themes made the theme
  picker wide enough to land on one, which is how it was found: by
  tests/frame.rs, which is the only mechanical guard the painted page has.
  ui::clear_panel now measures the edge before clearing — clearing is what
  destroys the evidence — and repaints the orphan.

Internal

• Theme::from_toml parses a theme from text already in hand;
  Theme::from_file is now a thin wrapper over it, so there is still one
  parser.
• render::highlight::has_syntax_theme reports whether the highlighter knows
  a syntax theme by name, which the bundled palettes are checked against.
• tests/docs.rs gained
  every_pinned_package_manifest_points_at_a_real_release, extending the
  Homebrew staleness guard to the AUR PKGBUILDs and the nix derivation.
• Two keyseq tests navigated the theme picker by counting j presses from
  slate to system, which only worked while exactly three themes shipped.
  They use G now, since system is the last row by construction. A picker
  wheel test asserted 3.min(len - 1) and passed for the wrong reason: the
  clamp hid the fact that the picker opens on the theme in force, not at the
  top.
