* improvement(tools): validate integrations, add Gong activity tools, regenerate docs

* fix(servicenow): give list-attachments limit a unique subBlock id

Read Records and List Attachments shared the subBlock id 'limit', so the
single-value-per-id store could bleed the value across operations. Rename
the new list-attachments field to attachmentLimit and map it back to the
tool's limit param.

* fix(servicenow): type upload-attachment response json to fix build typecheck

secureFetchWithValidation's response.json() resolves to unknown under the
build's stricter typecheck; cast the parsed body so data.result is accessible.

* refactor(servicenow): type upload-attachment response per file-route convention

Match the SharePoint/OneDrive upload pattern: import the named
ServiceNowAttachment type from the tool's types, cast response.json() to it,
and extract specific fields with ?? null instead of passing data.result
through as an opaque unknown blob.

* fix(servicenow): remove invalid 'custom' generationType from groupBy wandConfig

'custom' is not a member of the GenerationType union, breaking the build
typecheck. No valid type fits a comma-separated field list, so drop the
wandConfig (consistent with the block's other field-list inputs).

* fix(servicenow): drop redundant hidden fileContent param from upload attachment

Per project rule, visibility:'hidden' is reserved for framework-injected
tokens, not user-supplied data. fileContent was a copied-over legacy
fallback with no caller (the block uploads via the canonical file/UserFile
path), so remove it from the tool, types, contract, and route.

* fix(dub): require a link selector for bulk update links

Bulk Update Links could run with only Update Data and no Link IDs or
External IDs, sending Dub a request with no target links and producing a
confusing API error. Guard the tool to throw a clear validation error when
neither selector is provided, and clarify the block placeholder.
