feat(deno): migrate avow-protocol npm → Deno (standards#253)

Class A (pure-Deno port) for ROOT manifest only. Deletes redundant
package.json — deno.json already covers all tasks via `deno run -A
npm:rescript` and full imports map for rescript / @rescript/core /
@rescript/react / react / react-dom plus local path-mapped deps.

`avow-protocol/telegram-bot/avow-telegram-bot/` package.json is a
PERMANENT npm/Telegraf carve-out (see standards/.claude/CLAUDE.md §npm
Exemptions Approved) and is untouched by this PR.

Refs: standards#253 STEP 3 (smallest-first batch).
