chore: stop building packages during install

[lilienblum]

Summary

• remove the prepare build hook from the core, commands, bindings, and SDK packages
• keep package compilation behind the existing explicit build commands

Why

A workspace pnpm install currently compiles all four packages as a lifecycle side effect. Bootstrap only needs dependencies installed, so that work is unnecessary and makes setup appear stuck.

The stable and dev npm release workflows already run pnpm build before publishing or packing. A prepack replacement would keep compilation implicit and duplicate those release build steps.

Validation

• fresh and repeated pnpm install --frozen-lockfile complete without invoking the package builds
• explicit builds succeed for core, commands, bindings, and SDK
• package-layout fixture passes all 28 packed-artifact and consumer checks
• Biome passes for the changed manifests

Linear: ALIEN-374

Greptile Summary

Removes install-time TypeScript compilation and makes required builds explicit.

• Removes prepare build hooks from the core, commands, bindings, and SDK packages.
• Builds TypeScript dependencies explicitly before Rust CI tests and addon release smoke tests.
• Makes Turbo test tasks depend on package and dependency builds.
• Adds a bindings-specific Turbo task dependency so tests build the native addon.

Confidence Score: 5/5

The PR appears safe to merge.

No blocking failure remains.
