fix(mcp): return view rows by default

[adityathebe]

View row handling evolved across two commits with conflicting assumptions.

1cd0b204 made response formatting default withRows to false, matching the opt-in schema at the time. bd5ae6b0 later changed the schema, fetch behavior, and tool description to make rows enabled by default, but left the response guard unchanged.

Calls explicitly sending withRows=true still returned rows. The bug affected callers that omitted the argument and relied on the advertised default: JSON Schema defaults do not populate req.Params.Arguments, so rows were fetched using the true fallback and then discarded by response assembly’s false fallback.

Align response assembly with the current true default while preserving explicit withRows=false as an opt-out.

Fixes #3433

Summary by CodeRabbit

• Bug Fixes
  • Table rows are now included in MCP tool responses by default, matching the documented behavior.
  • Callers can still exclude rows by explicitly setting withRows=false.

Walkthrough

The MCP view handler now includes table rows by default. Callers can exclude rows by setting withRows=false.

Changes

MCP view response behavior

Layer / File(s)	Summary
Enable rows by default mcp/views.go	viewRunHandler now defaults withRows to true. Responses include table rows unless the caller sets withRows=false.

Merge Risk: ⚪ Minimal · up to c6870

Omitting the option now returns view rows as advertised while explicit false remains an opt-out; no actionable merge-blocking risk remains beyond normal checks and review.

Add a regression test for the omitted withRows case.

The current integration test passes "withRows": true, so it does not verify this new default. Add a case that omits withRows and asserts that the response contains rows. Also verify that "withRows": false excludes rows.
