fix(tool-web): align fetch card truncation, drop view content copies, sync card docs

Address the code-review bot findings on the web result card:
- web_fetch's card truncated now derives from the shared renderFetchOutput
  helper, matching the effective truncation the model-facing text reflects
  (provider cap, source cut, or output cap), instead of the provider-only flag.
- Drop the redundant content copy from both web result views; a UI without the
  web capability falls back to the raw tool/result content. Narrow the TUI
  transcript view.content access accordingly.
- Set the result-state title from the call args (query/url) so a window-
  truncated replay keeps a title.
- Project meta from the seam result types rather than hand-rolled value types.
- Sync the card vocabulary across core tools README, docs/core-data-structures,
  the adding-a-tool cookbook, and the tool-web package README (both languages,
  re-recorded pairings); regenerate the cordis api-catalog and cordis-inspect
  snapshot; revise the Agent Note.
