Upgraded several dependencies, including `go-ytdlp`, `go-crypto`, and `x/sys`, in `go.mod` and `go.sum`. Added `ulikunitz/xz` as an indirect dependency. Re-enabled `ytdlp.MustInstall` in the YouTube agent.
Deleted the `console_new` package, including its agent, container, execution, and utility files. Updated dependencies and replaced references to align with the maintained code structure.
Moved the Knowledge struct and related types to the shared package, updating all references across the codebase. This improves modularity and enables better reuse of the Knowledge type across different components.
Introduced a new tool for extracting YouTube video transcripts and leveraging them to answer questions. Updated `SearchAndRead` to support reading YouTube transcripts and regular pages distinctly. Included relevant dependencies for handling subtitles and video downloads.
