docs: Missing documentation

[aleksanderkatan]

Make it so the reference api is always after manual docs when searching.
READMEs for packages can also be updated.

• (Getting Started) Unplugin & tsover as core steps, not as tips.
• (Roots) Move enabling features closer to this section, or even merge the sections together.
• (Functions) Mention that tsover is completely optional.
• (Functions) Be more clear about what is and is not allowed in TypeGPU functions in supported JS functionality.
• (Functions) A section about what becomes const, var and let.
• (?) d.ref, and also notes about when we copy/reference variables and parameters.
• (Functions) Mention that std mirrors WGSL stl, and mention new functions.
• (Functions) Mention that functions implemented in JS don't need $uses.
• (Functions) Clarify builtins in shellless entry.
• (Functions) Give more JS examples.
• Maybe split Functions into Functions and Entry Functions, or just move entry functions to Pipelines.
• Use the "minimal entry that references more complex function" pattern in docs.
• (Pipelines) Reference Vertex Layouts since we use them.
• (Vertex Layouts) Full docs refresh.

• (Buffers) The synergy with Accessors.
• (Getting Started) Note that you can filter examples by used APIs.
• (Textures) The first snippet needs 'render' usage.
• (?) Once SWM has the agent skills repo, link it somewhere.
