docs(tools): fix cross-module JSDoc links and the catalog source list

Codex review of the vocabulary relocation found two doc-accuracy issues:

- presentation.ts's JSDoc used {@link ToolDefinition...}, which the
  TypeScript language service cannot resolve because presentation.ts
  deliberately does not import index.ts (that would create the cycle the
  split avoids). Demote those three to plain `ToolDefinition` code text;
  same-file and imported @links (TerminalResultView, ContentBlock) stay.
- docs/core-data-structures/tools.md's source header listed only index.ts
  and schema.ts; add presentation.ts, which now owns the presentation
  vocabulary the page documents.

 The tool pipeline of [dsh-tools](../../packages/core/tools). [core.md](core.md) introduces `ToolDefinition` as the one pipeline-authoring type promoted to the spine and `ToolSchema` as the model-facing wire shape. This page owns the full `ToolDefinition`, the typed schema DSL that builds it, the waterfall execution shapes, and the UI-presentation vocabulary.
