ci(packages): upload .deb/.rpm/.apk as release assets in packages-linux.yml

[satwareAG-ironMike]

Context

Attach all native package artifacts (.deb, .rpm, .apk) to the GitHub Release alongside the existing .tar.gz bundles. This enables users who don't have our APT/YUM/APK repo configured to download and install manually via wget + dpkg -i / rpm -i / apk add --allow-untrusted.

Acceptance Criteria

• packages-linux.yml release job uploads .deb, .rpm, .apk files as GitHub Release assets
• Assets named: php-firebird-13.0.0-php84-nts-debian-bookworm-amd64.deb, etc.
• Assets uploaded with draft: true (same as .tar.gz bundles)
• publish-release.yml publishes all assets when it flips draft: false
• Total asset count increases from 147 to ~147 + 32(.deb) + 12(.rpm) + 4(.apk) = ~195

Dependencies

• Release 6.2.0 Validation - All 85 Tests Passing #7, Feature: Stream Support for BLOB Parameters #16 (packages-linux.yml) — builds the packages
• Existing publish-release.yml workflow — handles the draft → publish flip

Suggested Test Plan

1. Tag a test release (e.g. v13.1.0-rc.1)
2. Verify GitHub Release includes .deb, .rpm, .apk assets
3. Download a .deb, install on clean Debian 12: dpkg -i *.deb
4. Verify php -m | grep firebird — loaded
