tasks/get examples under "Task Execution Errors" use "resultType": "task"; prose and schema require "complete"

The issue points to two specific lines in specification/2026-07-28/tasks.md and specification/draft/tasks.md where the examples incorrectly use "resultType": "task". The fix is to change them to "resultType": "complete" as shown in the diff. Verify the changes by checking the surrounding examples and the normative text. Run any documentation linting or validation scripts if present.

What's wrong

Two example responses in Task Execution Errors show a tasks/get result with "resultType": "task":

• specification/2026-07-28/tasks.md:846, in "Example: Task with JSON-RPC execution error"
• specification/2026-07-28/tasks.md:870, in "Example: Tool call completed with tool error (isError: true)"

specification/draft/tasks.md has the same text at the same line numbers.

Both are tasks/get responses. The section says so (tasks.md:835: "The tasks/get response SHOULD include a statusMessage…"), and the text after the second example calls it "The tasks/get endpoint" (:889).

The normative text says the opposite:

• tasks.md:338: "The resultType field MUST be set to "complete" on this object as it is the standard result shape for the tasks/get request."
• tasks.md:102: "Servers MUST NOT set resultType to "task" on result types other than CreateTaskResult."
• schema/2026-07-28/schema.ts:224 and schema/draft/schema.ts:224: GetTaskResult has resultType: "complete";.

The other tasks/get examples in the same file already use "complete" (:577, :610, :655, :733, :762).

Why it matters

Implementers copy examples. A client that switches on resultType and treats "task" as "this is a CreateTaskResult, start polling" would handle a terminal tasks/get response as a new task handle. A server built from these examples would break the MUST at :338.

Apply the same two changes to specification/draft/tasks.md (same line numbers). Nothing normative changes.
