fix(updater): prepare 1.3.15-Beta.2 after repository transfer

[appergb]

User description

Goal

Fix the release-blocking stale GitHub repository owner after the transfer from appergb/openless to Open-Less/openless, and prepare 1.3.15-Beta.2 for validation.

This updates desktop and Android updater endpoints, release workflows, updater-manifest generation, Homebrew/download/help links, and adds a repository-owner regression contract.

Compatibility impact

• No settings, data, schema, or API migration.
• Release version advances from 1.3.15-Beta.1 to 1.3.15-Beta.2 because the candidate code changed.
• Existing stable users continue to follow the stable updater manifest.

Verification

• npm test — passed; 23 frontend/contract tests discovered.
• node scripts/repository-owner-contract.test.mjs — passed.
• cargo test --locked --manifest-path src-tauri/Cargo.toml android::updater_logic::tests --lib — 8 passed.
• cargo test --locked --manifest-path src-tauri/Cargo.toml --lib -- --test-threads=1 — 727 passed; one aggregate-only thread-spawn Resource temporarily unavailable failure. The exact test passed when rerun alone.
• INSTALL=0 ./scripts/build-mac.sh — passed; generated OpenLess.app and OpenLess_1.3.15-Beta.2_aarch64.dmg.
• codesign --verify --deep --strict — passed for the local macOS bundle.
• Manual macOS launch — overview rendered and displayed v1.3.15-Beta.2.
• New stable updater endpoint — redirect chain completed with HTTP 200; legacy owner endpoint reproduced HTTP 404.

Issue / QA context

No linked issue. Found during the 1.3.15-Beta.1 release-candidate QA pass while checking the packaged app and updater logs.
