Release v0.7.6.8

Changelog for 0.7.6.8

• 2026-08-22

Added

• ohub source verify <name> subcommand — validates a custom source by fetching it and confirming it serves installable content. GitHub sources check for releases with assets; manifest sources verify a parseable JSON list. No external tools required; uses the existing Downloader + requests.
• Progressive timeout fallback — the --timeout flag (default 90s from config check_timeout_seconds) supports progressive query fallbacks via _progressive_queries() and _clean_app_query() helpers; if the first (cleaned) search times out or returns no results, the loop automatically tries progressively shorter cleaned names, then the raw name, before giving up. Wired into the unmanaged apps loop in cmd_check.
• --json flag on ohub check — already existed; outputs results as JSON via print(json.dumps(results, indent=2)) instead of human-readable lines. No code change needed; flag was already implemented.

Fixed

• Installing a ZIP-only release no longer crashes. ohub install <owner/repo> for a repo whose latest release contains only a .zip (no MSI/EXE setup) failed with 'Namespace' object has no attribute 'name' / "Failed to install archive". Root cause: the install command read parsed.name, but the install subparser has no --name flag (only add does). Fix: fall back to the repo name via getattr(parsed, "name", "") or repo. Regression tests added.
