docs: add build instructions and fix build pipeline

- Add README.md with setup, build, run, and typecheck instructions
- Install missing optional deps (OpenTelemetry exporters, AWS SDKs, sharp, etc.)
- Add missing internal source stubs (agents-platform, REPLTool, etc.)
- Add missing prompt.txt asset for ultraplan
- Fix build script with MACRO --define flags for bundled output
- Add createClaudeForChromeMcpServer export to chrome-mcp stub
- Verified: bun run start, bun run build, bun dist/cli.js all work

+# Claude Code (Source Build)
+
+TypeScript/React CLI application built with Bun.
+
+## Prerequisites
+
+- [Bun](https://bun.sh/) >= 1.3
+
+## Setup
+
+```bash
+cd src/
+bun install
+```
+
+## Running
+
+Run the CLI directly from source (development mode):
+
+```bash
+bun run start
+# or with arguments:
+bun run start -- --help
+bun run start -- --version
+```
+
+## Building
+
+Bundle into a single JS file:
+
+```bash
+bun run build
+```
+
+This produces `dist/cli.js` (~26 MB) which can be run standalone:
+
+```bash
+bun dist/cli.js --help
+```
+
+## Type Checking
+
+```bash
+bun run typecheck
+```
+
+**Note:** TypeScript reports errors due to ~120 internal source files that were not included in the source archive and are replaced with stubs. These do not affect runtime behavior.
+

+## Notes
+
+- The project uses `bun:bundle` feature flags for dead code elimination at build time
+- `MACRO.*` constants are injected at build time via `--define` flags (see build script)
+- For development, `preload.ts` provides these constants at runtime
+- Internal `@ant/*` packages are stubbed since they are not publicly available
