Expand snippet pool with more code and add lore/flavor text

8 more entries (16 total, up from 8): three more code snippets across
delve-term/stash/goonk for variety, plus five real lore/flavor text
fragments -- two from adventure's Chronicle of the Keepers (English)
and three from djupet's event log (Swedish, on purpose -- genuinely
different character set, and it's real shipped content, not filler).

Added a `type` field (code/lore) to every entry for future use (could
filter by type later) and updated the header/help-modal copy to stop
saying "code" exclusively now that it isn't.

Verified via simulated typing: a full Swedish snippet (öäå included)
types and finishes correctly with 100% accuracy, and a lore snippet
renders and completes the same as any code one.
