Struct LspInlayHintCache 

pub struct LspInlayHintCache {
    pub document_version: u64,
    pub hints: Vec<InlayHint>,
    pub requested_first_line: u32,
    pub requested_last_line: u32,
}

4.4.g: cached textDocument/inlayHint response for one buffer. Keyed on (BufferId, document_version); pump invalidates when the version changes. hints are sorted by position so the renderer can stop scanning once it walks past the current line.

4.4.g viewport polish: requested_first_line / requested_last_line (inclusive, 0-based LSP line indices) record the line range that produced this cache entry. The pump refetches when the visible viewport scrolls outside this window plus an overscan margin – so small scrolls stay cached, larger ones trigger a new request bounded to the new viewport. Small files where viewport + overscan covers the whole buffer cache exactly once and never refetch on scroll.
