fix(vscode): restrict feedback session IDs to the kilo provider

`isKiloGateway` used `startsWith("kilo")` which matches fictional
aliases like `kilo-dev`/`kilocloud`. The only real gateway provider
ID in the codebase is plain `kilo` — every other usage of it checks
`providerID === "kilo"`. Tighten to an exact match and drop the
`isKiloGateway` tests (it is now a one-line equality check) along
with the fabricated alias case in `buildFeedbackProperties`.
