feat(migration): Migrate from Node.js to Deno runtime

Major migration to Deno runtime following the nupst project pattern:

Core Changes:
- Created deno.json configuration with tasks, imports, and settings
- Created mod.ts as main entry point with Deno permissions
- Updated all TypeScript imports from .js to .ts extensions
- Replaced Node.js APIs (process.exit) with Deno equivalents (Deno.exit)
- Updated path imports to use @std/path from JSR

Dependencies:
- Migrated all npm dependencies to use npm: prefix in import map
- Added Deno standard library imports (@std/path, @std/assert)
- Configured import aliases for all @push.rocks and @serve.zone packages

Build & Distribution:
- Created install.sh for downloading pre-compiled binaries
- Created uninstall.sh for clean system removal
- Created scripts/compile-all.sh for multi-platform compilation
- Supports Linux (x64, ARM64), macOS (x64, ARM64), Windows (x64)

Testing:
- Migrated tests to Deno test framework using @std/assert
- Created test.simple.ts for basic verification
- Updated test structure to use Deno.test instead of tap

CI/CD:
- Created .gitea/workflows/ci.yml for type checking, linting, and builds
- Created .gitea/workflows/release.yml for automated releases
- Created .gitea/release-template.md for release documentation

Cleanup:
- Removed package.json, pnpm-lock.yaml, tsconfig.json
- Removed Node.js CLI files (cli.js, cli.child.ts, cli.ts.js)
- Removed dist_ts/ compiled output directory
- Removed npmextra.json configuration

This migration enables standalone binary distribution without Node.js
runtime dependency while maintaining all existing functionality.
