refactor(ev): organize internal build domains

[xusd320]

Summary

• Group @evjs/ev internal build modules by capability instead of keeping a flat directory.
• Preserve the supported @evjs/ev/_internal/build export surface and runtime behavior.

Changes

• Add focused domains for analysis, conventions, discovery, config loading, development, generated IR, output, plugins, type generation, bundler contracts, and command operations.
• Turn commands.ts, graph/index.ts, plan/index.ts, and transforms/index.ts into thin façades.
• Extract graph, plan, and transform contracts into type-only leaf modules and use leaf imports between domain implementations.
• Update all repository consumers, adapter tests, architecture guidance, and ownership tables to the new paths.
• Add a package-surface guard for the build-root taxonomy and façade boundaries.

Validation

• GitHub Actions CI — passed, including build, lint/typecheck, unit, and E2E.
• npm run check-types — 31/31 tasks passed.
• npm run lint — 514 files checked.
• WATCHPACK_POLLING=true npm test -- --env-mode=loose — 17/17 tasks passed, including EV 814 tests, Utoopack 87 tests, and Webpack 86 tests.
• npm --workspace @evjs/ev test -- tests/build-tools-transforms.test.ts — 43 tests passed.
• git diff --check.

Risk / rollout

• No public API, configuration, data, or migration changes.
• This is rename-heavy and updates repository-owned deep internal imports; unsupported external deep imports to the old physical paths would need to follow the curated internal build barrel.
• Polling was used for the full local test run because native Watchpack file watching hits the Codex sandbox's file-descriptor limit.

Reviewer notes

• Focus review on the capability mapping, the config-loader relative runtime paths, and façade export equivalence.
• Further decomposition of the command implementation by transaction lifecycle can follow separately; this PR establishes the domain boundary without mixing in behavioral changes.
