v1.3.0: scorecard + mobile fix, fold in PRs, esbuild + nix flake

Polishes the plugin to clear the community-plugin-page scorecard
(60% HealthFair/ReviewCaution) and resolve the open issue/PR backlog.

Rendering

• Drop Buffer (Node-only, threw on mobile) for chunk-safe browser
  base64 (0x8000-byte chunks, then btoa). Fixes Diagrams don’t render on Obsidian mobile #8.
• Drop dest.innerHTML = result (the headline scorecard flag).
  Desktop now fetches the SVG via request(), parses with DOMParser,
  and appends the parsed so in-SVG links / imagemaps stay
  clickable (obsidian internal links not working for graphviz #9). On mobile (Platform.isMobile) or on any parse
  failure, fall back to

Folded-in PRs

• @from_file: include keyword (PR add include option and resizing #25), via
  getAbstractFileByPath + instanceof TFile + cachedRead (no
  minAppVersion bump). Missing file -> inline .kroki-error.
• Per-diagram PNG download + niolesk Edit links (PR add png link and niolesk png button #19 #20), built with
  DOM helpers, styled in styles.css.
• New diagram types DBML, Symbolator, TikZ (PR Updates #23) + kroki-test.md
  examples; replace the broken UMlet example with a working
  modern-schema one ( / UMLClass).
  Wrap the TikZ example in \documentclass{standalone} + \begin{document}.
• Browser base64 (PR switch to browser base64 methods #26) -- superseded by the chunk-safe implementation.

Per-type header inputs

• The legacy single 'header' setting (inherited from upstream
  obsidian-plantuml, never actually applied here) was the wrong shape:
  each of the four languages that accept top-of-source directives
  (PlantUML, C4-PlantUML, Structurizr, Mermaid) has its own syntax,
  and the other ~25 types break on any prelude.
• Replace it with settings.headers: Record<kroki, string>, populated
  via a dedicated full-width textarea inside each supported diagram
  type's own settings card. Per-type placeholder + help text.
• Diagram types not in HEADER_SUPPORTED_TYPES show no header field
  and receive no prepend.
• loadSettings migrates the legacy 'header' value into
  headers.plantuml on first load and drops the old field.

Settings tab

• Setting.setHeading() instead of raw createEl("h3") /

  .

• New 'White background' toggle adding .kroki-bg-white (Change background color? #2 -- helps
  with transparent SVGs on dark themes).
• Per-type inline header textarea (full-width, vertically resizable,
  monospaced) inside each supported diagram type's card.
• Remove all console.log; remove dead img/useMap code; remove the
  unused 'toggle' field that was being persisted into data.json.

Styles

• New CSS: .kroki-diagram (centered, max-width:100% -- Scaling #7),
  .kroki-bg-white, .kroki-actions, .kroki-error, .kroki-header-row,
  .setting-item.kroki-with-header (flex-wrap to let the header row
  sit full-width).

Build + dev shell

• rollup -> esbuild (esbuild.config.mjs); delete rollup.config.js.
• Bump deps: typescript@5, @types/node@22, eslint@8 +
  @typescript-eslint@7, pako@2, tslib, esbuild, builtin-modules.
• Modernise tsconfig.json: target ES2018, strictNullChecks,
  isolatedModules, skipLibCheck.
• Add Nix flake dev shell (flake.nix + flake.lock + .envrc) with
  Node 22 via nix develop.

CI / release workflows

• main.yml + publish.yml: actions/checkout@v4, actions/setup-node@v4
  with Node 22, npm (not yarn), softprops/action-gh-release@v2.
  Drop the deprecated actions/create-release@v1 +
  actions/upload-release-asset@v1 and the ::set-output usage.
• publish.yml now uploads only main.js / manifest.json / styles.css
  (no zip -- Obsidian doesn't need it).
• main.yml also runs npm run build so type errors fail CI.

Docs

• README: new 'Supported diagram types' table near the top (all 29
  types, linked to their upstream projects, with notes for the three
  default-disabled types).
• README + kroki-test.md: note that diagramsnet requires a self-hosted
  Kroki with the yuzutech/kroki-diagramsnet companion (public kroki.io
  returns 503), and that mermaid / plantuml are disabled by default to
  avoid clashing with Obsidian / the PlantUML plugin.
• README: explain the per-type inline header inputs.

Version

• manifest.json + package.json -> 1.3.0.
• versions.json adds "1.3.0": "0.13.25" (minAppVersion unchanged).

Closes #2, #7, #8, #9. Supersedes PRs #20, #23, #25, #26.
