fix: build review before hook in root build

[rNoz]

Closes #1388.

Rationale

apps/hook copies the review bundle during its build, so a clean checkout cannot run the root bun run build command when the review app has not already been built.

Change scope

Update the root package.json build script to run build:review, then build:hook, then build:opencode.

Validation

On a clean Linux checkout with Bun, bun install --frozen-lockfile completed, bun run build:review completed, and the corrected bun run build completed.

Explicit omissions

This change does not alter the hook build script, generated bundles, package dependencies, or runtime behavior. Generated node_modules and dist outputs were removed after validation.

[rNoz]

Rebased this one-line build-order fix onto current main and reverified it from a clean checkout with no pre-existing review or hook bundles.

Validation:

• PATH="$PWD/apps/hook/node_modules/.bin:$PATH" bun run typecheck passed (Bun's isolated linker does not expose a root tsc)
• root bun run build passed after bun install --frozen-lockfile
• full suite: 4,021 passed, 756 skipped, 3 failed locally; two failures passed in isolation, and the remaining combined-workspace-diff failure reproduced unchanged on a clean upstream/main checkout

The PR still changes only the root package.json build sequence: review, then hook, then OpenCode.
