/model and /scoped-models listed only `id [provider]`, so renamed
overrides from models.json were invisible in the list. Rows now show
the name in parentheses when it has words the id lacks, e.g.
`minimax/minimax-m3 (MiniMax M3 [parasail]) [openrouter]`. Names that
only restate the id with different casing, separators, or a dropped
namespace/version suffix stay hidden.

fuzzyMatch scored only the greedy leftmost alignment, so a query could be
scattered over an earlier unrelated part of the text (opus via "openrouter",
astra via "radius radius/gpt") and the real match ranked last. It now also
scores every contiguous occurrence and keeps the best alignment.
/resume matched one concatenated id/name/messages/cwd string. Scattered
matches in megabytes of message text or in UUIDs were noise, and the
position penalty buried real hits deep in a transcript. Fields are now
matched separately: name and cwd fuzzy, id and messages exact only, with no
position penalty. Ranking is name text, then id/message/cwd text, then
scattered name/cwd matches. Lowercased message text is cached per session.
