chore(deps): remove unused dependencies

[gkriegspeedbay]

What

Removes 8 dependencies that are declared but never used:

• dependencies: file-type, remark, remark-gfm, remark-parse, unified
• devDependencies: commander, ts-node, nexe

Why

None of these are imported in source, invoked by an npm script, or referenced in any config. Removing them drops ~4,900 net lockfile lines — the unified/remark markdown stack, file-type, and nexe's large stalled-beta subtree (archiver@5, got, caw, download, @yarnpkg/*, app-builder, …). nexe's latest dist-tag is still a 2025 beta and nothing in the repo invokes it.

Kept (depcheck flags them, but they ARE used)

• @tiptap/pm — a required peerDependency of @tiptap/core and @tiptap/extension-table.
• @anthropic-ai/mcpb — invoked by the build:mcpb script via npx @anthropic-ai/mcpb validate|pack.

Verification

With all eight removed: npm install resolves, npm run build (tsc over the full source tree) succeeds — proving nothing in src imports them — and exceljs round-trips pass.

📝 Walkthrough

Walkthrough

package.json removes file-type from dependencies and removes commander, nexe, and ts-node from devDependencies. Additionally, sharp and tiptap-markdown are repositioned before the remark-related entries in dependencies; their versions are unchanged.

Poem

🐇 Snip snip, out go the strays,
file-type hops along its way,
nexe and commander bid adieu,
ts-node vanished from the queue.
Fewer deps, a tidier burrow—
less to chew through tomorrow! 🌿
