体验：catalog 无匹配只报 No tracked tools，不说下一步

体验问题：catalog 搜不到工具时没有下一步

Skip: doctor vs diagnose help (#54) and inherited --no-progress (#55). This is a different command.

Current design

all-cli catalog [search] lists the built-in tool catalog without running those tools. A miss prints:

No tracked tools match "not-a-real-tool".

all-cli describe already suggests a nearby ID (did you mean "kubectl"?). Catalog does not. It also does not say how to list the full catalog or how to inspect one tool.

--ids on a miss prints nothing at all. Human mode at least says there was no match, then stops.

Why this is a problem

1. First-time users treat catalog as the discovery surface. A typo or category word that is not a substring looks like an empty product.
2. The next useful commands already exist: all-cli catalog with no query, and all-cli describe <id>.
3. Agents parsing human output get a dead end instead of a recovery command.

Suggested change

On a human-mode empty search, print the miss, then one recovery line: list the catalog, or did you mean plus all-cli catalog <id> when toolIDSuggestion has a hit. Leave --json and --ids machine shapes unchanged.

Do not change doctor/diagnose help in this pass.

Start at the all-cli catalog command and compare its human-mode miss path with all-cli describe's suggestion behavior. Check the no-query catalog output and toolIDSuggestion handling; done means human empty searches show a recovery line while --json and --ids remain unchanged, with doctor/diagnose help unaffected.
