The bare `msdl` invocation showed all 22 products (17 consumer + 5 eval) as a flat numbered list. Replaces it with a curated landing screen: 5 popular products (picked from real usage telemetry) plus a 2-item eval shortlist, with "list" as an escape hatch to today's full picker and free text routed through the existing search flow. Also fixes a search bug: querying "windows 10" incorrectly matched Windows 11 24H2 because "10" is a substring of its build number (26100.1742). Query words now must start at a word boundary rather than matching anywhere, so digit fragments inside unrelated numbers can no longer collide -- while "arm" still fuzzy-matches "ARM64".
