Rename SnapshotGenerationOverrides -> TendermintSnapshotGenerationOverrides

[bdchatham]

Context

SnapshotGenerationOverrides(keepRecent int32) map[string]string currently lives in this repo and is consumed by sei-k8s-controller's planner to set snapshot-interval / snapshot-keep-recent on app.toml.

In sei-k8s-controller we just landed a refactor (sei-protocol/sei-k8s-controller#108) that nests the controller-side config under a TendermintSnapshotGenerationConfig sub-struct, so the "Tendermint state-sync snapshot" mode is explicit and extensible for future snapshot flavors (e.g., seidb, app-layer).

Request

Rename SnapshotGenerationOverrides → TendermintSnapshotGenerationOverrides to match. This is small and mechanical but clarifies the function name aligns with the only snapshot mode it writes overrides for — the Tendermint state-sync one.

Not blocking anything; filing so it doesn't get lost.

Call sites to update after the rename

• github.com/sei-protocol/sei-k8s-controller/internal/planner/archive_test.go (references KeySnapshotInterval nearby)

Suggested shape

// TendermintSnapshotGenerationOverrides returns app.toml overrides that
// configure seid to produce Tendermint state-sync snapshots at the system
// default interval, retaining `keepRecent` on disk.
func TendermintSnapshotGenerationOverrides(keepRecent int32) map[string]string { ... }

Keep the old name as a deprecated alias if any external consumer is known, or just rename outright — sei-k8s-controller is the only in-tree caller I'm aware of.
