fix(build): add root package.json so bench builds the SPA

[Rl0007]

Problem

On a fresh bench get-app + bench build --app wikify, no frontend assets were produced. The build reported success in ~300ms and emitted nothing — no bundle, and no wikify/www/wikify.html, so /wikify returned Page not found.

Cause: frappe's esbuild runner looks for apps/<app>/package.json and silently continues when it's missing — frappe/esbuild/esbuild.js:611-620:

let package_json = path.resolve(root_app_path, "package.json");
if (!fs.existsSync(package_json)) {
    continue;          // <- wikify fell through here
}
let { scripts } = require(package_json);
if (!scripts?.build) {
    continue;
}

frontend/package.json exists, but the root one never did — so the app was never a build candidate.

Fix

• Add the root package.json with the standard Frappe SPA scripts, matching frappe/crm.
• postinstall cascades into frontend/, which also keeps frontend deps in sync. Worth calling out: without it, a stale frontend/node_modules silently builds against the wrong frappe-ui — on this branch that surfaced as 12 MISSING_EXPORT errors (BottomSheet, etc.) because beta.18 was installed while frontend/package.json had moved to beta.24 in 16f5f55.
• Ignore wikify/public/node_modules. bench build symlinks it, and git sees a symlink rather than a directory, so the existing node_modules/ rule never matched it and it showed up as untracked.

yarn.lock is the trivial autogenerated root lockfile (2 comment lines), same as crm's.

Verification

Reproduced and fixed against wikify.localhost, each run from a cleared wikify/public/frontend + wikify/www/wikify.html:

state	bench build --app wikify	assets	www/wikify.html
without root package.json	Total Build Time: 315ms — no build command run	0	missing
with root package.json	✔ wikify built in 14.9s	81	emitted

/wikify renders correctly after the fix (Projects list, sidebar, styling all intact). pre-commit passes on the changed files.

Greptile Summary

Adds the root package metadata needed for Frappe Bench to discover and build the SPA, while declaring Wiki as a required app.

• Cascades root dependency installation and build commands into frontend/.
• Installs the Wiki dependency in CI before Wikify.
• Ignores Bench-generated dependency symlinks and reformats existing source files.

Confidence Score: 5/5

The PR appears safe to merge because no blocking failure remains.
