Building and maintaining a search index costs storage and periodic upkeep, and the index can lag behind the real files. For occasional searches that is overkill. Add a new search_index option "no_index" backed by a searcher that, instead of querying a prebuilt index, walks the filesystem under the requested parent on each search (bounded by max_index_depth, ignore_paths and a 1000-result cap) and matches object names against the keywords with the same case-insensitive AND semantics as the indexed backends. Index mutating methods are no-ops and AutoUpdate is off, so nothing is persisted. Existing permission/hidden-path filtering in the search handler still applies to the results. Closes AlistGo#9468

需求 / Motivation
构建并维护搜索索引需要额外存储与定期维护，且索引可能滞后；对偶尔搜索的场景过重。对应 #9468。
改动 / Change
在「搜索索引」设置新增
no_index选项。选中后搜索不再查预建索引，而是从当前目录用fs.WalkFS实时遍历子树、对文件/目录名做关键词匹配（大小写不敏感、AND 语义，与索引后端一致）：max_index_depth、ignore_paths约束，并对单次结果封顶 1000 条（提前中止遍历），避免大网盘打爆内存/耗时；Index/BatchIndex/...均为 no-op，AutoUpdate=false）；Init/中间件无需改动（仅精确等于none才禁用搜索）。默认仍为none，零回归，需用户手动切到 No index 才启用。验证 / Verification
go build ./...、go test ./internal/search/noindex/通过。Closes #9468
