fix(build): use tsc --build to respect dependency order in monorepo

[jlia0]

Description

Fix build failures after the monorepo refactoring by respecting TypeScript project reference dependencies. The previous build script used npm run build --workspaces which runs all workspace builds in parallel, causing dependent packages to fail when @tinyclaw/core hadn't finished building yet.

Changes

• Changed root build script from npm run build --workspaces to tsc --build
• This respects the project references already configured in each package's tsconfig.json
• Builds packages in correct dependency order: core → teams → channels/server → main

Testing

• ✅ Build completes successfully
• ✅ All TypeScript compilation errors resolved

Greptile Summary

This PR replaces the parallel npm run build --workspaces root build script with tsc --build to leverage TypeScript project references and enforce correct dependency ordering across the monorepo. The approach is sound — the root tsconfig.json is already properly configured as a solution-style file ("files": [] + "references") and tsconfig.base.json provides "composite": true for all packages that extend it.

However, one blocking issue was found:

• packages/visualizer/tsconfig.json is incompatible with composite project references. Unlike every other package, it does not extend ../../tsconfig.base.json, missing the required "composite": true. It also explicitly sets "declaration": false, which TypeScript forbids in a composite project. Since the root tsconfig.json includes packages/visualizer in its references array, tsc --build will error with TS6306: Referenced project must have setting 'composite': true when it reaches the visualizer package.

Confidence Score: 2/5

• Not safe to merge as-is — tsc --build will fail on the visualizer package due to missing composite: true.
• The fix correctly identifies the problem (parallel workspace builds racing) and the solution (tsc --build with project references) is the right approach. The root tsconfig.json and all package configs except one are properly set up. However, packages/visualizer/tsconfig.json lacks composite: true and sets declaration: false, which will cause a hard TypeScript error when tsc --build processes it, blocking the build entirely.
• packages/visualizer/tsconfig.json — must be updated to extend tsconfig.base.json and remove declaration: false before this PR can work end-to-end.

Important Files Changed

Filename	Overview
package.json	Root build script changed from npm run build --workspaces to tsc --build. The intent is correct and the root tsconfig.json is properly configured with "files": [] and references for all packages. However, packages/visualizer/tsconfig.json lacks composite: true and sets declaration: false, which will cause tsc --build to fail when it processes the visualizer reference.

tsc --build will fail for the visualizer package

packages/visualizer/tsconfig.json is not compatible with TypeScript composite project references, which tsc --build requires for every entry listed under references in the root tsconfig.json.

Two problems with the visualizer's config:

1. It does not extend ../../tsconfig.base.json, so it does not inherit "composite": true.
2. It explicitly sets "declaration": false — which is incompatible with composite: true (TypeScript requires declarations to be emitted for composite projects so downstream packages can consume them).

When tsc --build reaches packages/visualizer, it will throw:

error TS6306: Referenced project 'packages/visualizer' must have setting 'composite': true.

All other package tsconfigs extend tsconfig.base.json (which provides composite: true and declaration: true), so only the visualizer is affected. The fix is to bring it in line with the rest of the packages:

{
  "extends": "../../tsconfig.base.json",
  "compilerOptions": {
    "outDir": "./dist",
    "rootDir": "./src",
    "jsx": "react-jsx"
  },
  "include": ["src/**/*"]
}

Note that isolatedModules can be dropped (it's a bundler-oriented option and not meaningful for tsc output), and declaration: false must be removed so the composite build can emit .d.ts files.
