[followup] AST walker resolveIncErrorCall: handle CallExpr cast form

[trilamsr]

Source: docs/followups/opportunistic.md row 8 (Next up).

runbook_kinds_test.go::resolveIncErrorCall (in components/receivers/kernelevents/) resolves IncError(kindFoo) (*ast.Ident) and IncError(selftelemetry.KindBar) (*ast.SelectorExpr) but not IncError(selftelemetry.Kind("foo")) (*ast.CallExpr cast). The kind would slip past the RUNBOOK parity check.

Trigger status (FIRED): call sites of selftelemetry.Kind("...") already exist in:

• internal/selftelemetry/capturing_test.go:52
• components/exporters/otlphttp/classify_internal_test.go:23,33,38

(None are inside an IncError(...) argument today, but the AST walker should still handle the cast form before a future caller introduces it.)

Files:

• components/receivers/kernelevents/runbook_kinds_test.go — extend resolveIncErrorCall switch with *ast.CallExpr case, recognize selftelemetry.Kind("literal").
• Same file in any other receiver that copies the pattern.

Acceptance:

• Adding a test fixture IncError(selftelemetry.Kind("test_kind")) in receiver.go surfaces "test_kind" in extractEmittedKinds.
• Existing RUNBOOK parity test still passes.

Note: the original follow-up cited the file as components/receivers/dcgm/runbook_kinds_test.go; correct path is components/receivers/kernelevents/runbook_kinds_test.go. DCGM uses docs_parity_test.go for an equivalent walker; both should grow the CallExpr handling.
