feat: export helpers used by sibling packages

[nrps9909]

Summary

• export CommonInputProps, useCount, and resolveOnChange from the package root
• add a root-export regression test
• keep the existing implementations and runtime behavior unchanged

Motivation

The sibling @rc-component/textarea package currently consumes these declarations and helpers through @rc-component/input/lib/* deep imports. The current father-plugin compile check rejects package-internal es/lib imports, so textarea cannot migrate to supported root imports until input exposes the symbols it already relies on.

HolderRef and BaseInputProps are already available from the root; this completes the remaining sibling-package surface without moving or duplicating implementation code.

Validation

• focused root-export test: 1 passed
• full suite: 11 suites, 128 tests, 22 snapshots passed
• npm run tsc
• npm run lint (0 errors; 2 existing hook warnings)
• npm run compile (ESM, CJS, declarations, and Less)
• generated ESM and CJS index.d.ts files expose all three symbols
• git diff --check

I checked every current open PR changed-file list; none modifies src/index.tsx or adds this root-export surface.

AI assistance disclosure: Codex was used to trace the sibling package compile failure, verify the current public exports, implement the root exports and regression, run validation, audit open PR overlap, and draft this description. All cited results were verified on the submitted head.

Merge Risk:⚪ Minimal · up to 15d04

The PR exposes existing helpers from the package root without changing their implementations or runtime behavior and adds regression coverage. No actionable merge-blocking risk remains beyond normal checks and review.

Poem

小兔检查根出口，
类型和函数排成行。
useCount 轻轻跳，
resolveOnChange 发新光。
空对象通过类型门，
测试落下安心章。
