feat(cpp): add standard installation layout and native packaging support

[ColinLeeo]

Background

The TsFile C++ build currently places its outputs primarily in the build directory. It does not provide a standard installation layout or sufficient metadata for downstream consumers and native package managers.

This pull request introduces a unified installation and packaging mechanism for the TsFile C++ library, command-line tools, headers, and development metadata.

Changes

• Add a standard CMake installation layout:
  • include/tsfile
  • lib
  • bin
  • lib/cmake/TsFile
  • lib/pkgconfig
• Export the TsFile::tsfile CMake target.
• Add TsFileConfig.cmake and package version metadata.
• Add the libtsfile.pc pkg-config file.
• Install the current C++ compatibility header closure while preserving the existing include relationships.
  • This pull request does not redefine the stable public C++ API boundary.
  • Public header cleanup will be handled separately.
• Add shared-library versioning:
  • Package version: 2.3.2
  • ABI/SOVERSION: 1
• Add a relative runtime path for tsfile-cli, allowing an installed prefix to be relocated.
• Fix static-library installation exports so they do not expose internal object-library targets.
• Restrict compatible system ANTLR4 versions to:
  • 4.9.3 <= version < 4.10.0
  • Incompatible system versions fall back to the verified bundled runtime when the dependency policy is AUTO.
• Add optional CPack configuration for TGZ, DEB, and RPM packages.
• Add a Homebrew Formula:
  • packaging/homebrew/tsfile.rb
• Add packaging documentation:
  • packaging/README.md
• Add installed CMake and pkg-config consumer tests.
• Add native Linux packaging CI:
  • Ubuntu generates DEB packages.
  • Fedora generates RPM packages.

Package Layout

The native packages are divided into three components:

• tsfile
  • Runtime shared library.
• tsfile-dev / tsfile-devel
  • C++ headers, CMake package files, and pkg-config metadata.
• tsfile-tools
  • Command-line tools.
  • Installs the tsfile-cli executable.

CI Artifacts

Debian/Ubuntu packages:

tsfile_2.3.2_<arch>.deb
tsfile-dev_2.3.2_<arch>.deb
tsfile-tools_2.3.2_<arch>.deb

Fedora/RHEL packages:

tsfile-2.3.2-1.<arch>.rpm
tsfile-devel-2.3.2-1.<arch>.rpm
tsfile-tools-2.3.2-1.<arch>.rpm

GitHub Actions artifact names:

tsfile-deb
tsfile-rpm

Verification

The following checks have been completed:

• An installed CMake consumer builds and runs successfully.
• An installed pkg-config C consumer builds and runs successfully.
• An installed pkg-config C++ consumer builds and runs successfully.
• ANTLR4 dependency resolution tests pass.
• A CPack TGZ archive is generated successfully on macOS.
• The Homebrew Formula passes Ruby syntax and style checks.
• The packaging workflow YAML is valid.
• git diff --check passes.
• tsfile-cli --version works from the installed prefix.
• The installed CLI continues to work after relocating the installation prefix.
• Installed CMake metadata does not expose source paths, build paths, or internal object-library targets.

Follow-up Work

This pull request deliberately preserves the current compatibility header closure to avoid breaking existing C++ and Python consumers.

A separate C++ public API cleanup will introduce a stable cpp/include/tsfile boundary and gradually remove internal implementation headers from the installation package.
