[owen-mc]

This should not be merged until we have update to use Go 1.24.

• Taint models have been added for the weak package, added in Go 1.24.
• Taint models have been added for the interfaces TextAppender and BinaryAppender in the encoding package, which were added in Go 1.24.

The models look good to me. I assume the test expectations need updating?

[owen-mc]

Actually the expectations don't need to be updated. These tests (originally generated by an external contributor using a tool) are written in a non-standard way, where these lines

		source := newSource(4)
		out := TaintStepTest_EncodingBinaryAppenderAppendBinary_manual1(source)
		sink(4, out)

indicate that we expect a flow from newSource(4) to out in sink(4, out), and if there isn't a flow then we get a result from the test query.

LGMT, just one small wording suggestion for the change note
