…9722) Follow-up to #19641 — step 2/N towards simplifying TOML reading at startup. ## Summary - **Lazy-parse webseed TOML**: instead of parsing all 8 chains' webseed TOML at init time, store raw bytes in `EmbeddedWebseedsRaw` and parse on demand via `GetEmbeddedWebseeds(chain)` — only the chain actually in use gets parsed. - **Remove no-op re-assignment**: `LoadRemotePreverified` was redundantly re-building the same `KnownWebseeds` map; removed. - **Inline `webseedsParse`**: folded into its sole caller `GetEmbeddedWebseeds`. - **Rename `KnownWebseeds` → `EmbeddedWebseeds`**: clearer naming — `EmbeddedWebseedsRaw` for the raw bytes map, `GetEmbeddedWebseeds()` for parsed access. --- **TODO**: cherry-pick to `release/3.4` after merge.
