Search output format aliases should be consistent across map, symbols, and inspect

[Widthdom]

Summary

While dogfooding, search advertises --format <...> but map, symbols, and inspect use different JSON/compact flag shapes. It is easy to try --format json consistently and get a parser failure.

Evidence

• cdidx search --help exposes --format <text|json|count|compact|csv|tsv|lsp|qf|sarif|issue-drafts>.
• cdidx map --help and cdidx symbols --help expose --json/--compact style flags instead.
• This makes scripted audit flows branch per command even when requesting the same output shape.

Expected

Either accept common --format json|compact|count aliases across these commands, or return a targeted hint that names the command-specific flag.
