sigil-lsp: warm the docs index at `initialized`

Message

The first textDocument/hover after server start used to lazily build the (sigil docs search) index by scanning ~130 JSON files on demand, which the timing log showed clocking in at ~7500ms per first hover. Moving the build to the initialized notification shifts that cost off the user's interactive path — the server responds to initialize immediately, then warms the index before the first real request arrives. Logged at info with its own elapsed-ms so we can still see the cost in the trace log.

(Also removes leftover [E]/[S] render markers from an earlier diagnostic round.)
