Server:
- Add date range filtering (start_date/end_date/date_field) and pagination to MCP search tool
- Add collectionId/collectedAt fields to McpPageItem and all builder paths in McpUtils
- Add structured filter fields (contentType, libraryFilter, alreadyRead, searchTitleOnly) to SearchQuery
- Add new MCP tools: ListCollections, ListCollectionContent, GetXSaveRules
- Refactor McpServerController tool dispatch with getToolArguments/executeTool helpers
- Refactor LuceneService search option resolution; add buildSearchDateRangeQuery

Extension:
- Add AbortSignal support to createAgentToolContext and MCP client loading
- Add getCurrentTimeTool for time-aware AI responses
- Add retry button to UserMessage component
- Increase agent tool loop max steps from 5 to 50

Client:
- Fix i18n: translate document titles and nav labels in settings pages and PageList
