feat(deno): migrate fogbinder npm → Deno (standards#253)

[hyperpolymath]

Summary

Class B (npm-wrapper via Deno) — simplest possible case in the smallest-first batch of standards#253 STEP 3.

• Deletes fogbinder/package.json stub (rescript-toolchain devDeps only, zero scripts, private: true).
• fogbinder/deno.json already self-contained — carries npm:rescript via imports map and has full task graph (dev/build/test/bundle/fmt/lint).
• Adds npm-avoidant entries (standards#67) to root .gitignore: package-lock.json, bun.lockb, yarn.lock, pnpm-lock.yaml, .npmrc.

Scope

Only fogbinder/ sub-tree + root .gitignore. No other workspaces touched.

Refs

• standards#253 (npm → Deno estate campaign, STEP 3)
• standards#67 (npm-avoidant gitignore policy)

Test plan

• fogbinder/deno.json exists and is self-contained (verified pre-commit)
• No remaining package.json/lockfiles under fogbinder/ (verified by ls fogbinder/)
• CI green on PR
