fix(packager): normalize Windows path separators in zip entries

Fix: Windows deployment - normalize TypeScript import paths

Problem

When deploying Rocket.Chat Apps on Windows using rc-apps deploy, the packaging step fails with a TypeScript error:
File 'RoomPersistence.ts' not found.

• The project compiles correctly with tsc.
• Deploys fine on macOS.
• The error occurs only when the main app entry imports additional modules.
• Root cause: the CLI Language Service cannot resolve Windows-style \ paths during packaging.

Solution

• Normalize all module paths in the packager to use POSIX-style / separators.
• Ensures TypeScript can locate all source files on Windows.
• Cross-platform safe: macOS and Linux deployments remain unaffected.
• But this thing require CLI installation fails on Windows because package.json scripts use Unix rm command #179 to be done , as it give Cross-Platforem safe work with help of remref (in Windows):
• "postpack": "rimraf oclif.manifest.json",
  "prepack": "rimraf lib && tsc && oclif-dev manifest && oclif-dev readme",
  "prepare": "rimraf lib && tsc",

Impact

• Windows deployments now succeed even with additional module imports in the main app entry.
• Deployment behavior is consistent across Windows, macOS, and Linux.

Testing

• Verified packaging succeeds on Windows with module imports.
• Verified macOS deployment continues to work as expected.
