release: 1.2.1

[jphan32]

Releases 1.2.1. Merging this pushes the bare 1.2.1 tag and publishes the GitHub release with attested main.js / manifest.json / styles.css.

Compliance only — no change in behaviour from 1.2.0.

Fixed

Two warnings raised by Obsidian's plugin review (PR #34):

• Elements are created through Obsidian's createEl helper instead of document.createElement (obsidianmd/prefer-create-el). The free function, not Node.createEl — the latter appends to the node it is called on, and the helper has to return a detached element.
• The inert footnote marker's dotted underline is written with the text-decoration-line / text-decoration-style longhands. Obsidian's CSS check flags the multi-value text-decoration shorthand as only partially supported at this plugin's minAppVersion.

Internal — recurrence prevention

Both findings existed as rules the local gate was supposed to enforce. It could not have caught either:

• eslint-plugin-obsidianmd was pinned at 0.3.0, which does not carry prefer-create-el — the gate was checking a strictly smaller rule set than the review it exists to pre-empt. Now 0.4.1, which reproduces the finding exactly.
• That rule reports at warning severity and eslint exits 0 on warnings, so even on 0.4.1 the gate would have passed. npm run lint now runs with --max-warnings=0.

Verified by reverting the fix: the hardened gate fails rather than warning.

The e2e bootstrap gained a createEl / Node.prototype.createEl stub written to the real signature rather than shaped to what the bundle happens to call.

Verification

npm run lint            PASS   (--max-warnings=0, plugin 0.4.1)
npm run build           PASS
node --check main.js    PASS
node scripts/validate.mjs   PASS   (versions.json has 1.2.1 → 1.6.6)
npm run test:e2e        PASS   119 checks (table 106, diagram 13)

minAppVersion stays 1.6.6. Users below it remain on 1.1.7 via versions.json.
