The bare `db*` .gitignore rule was overly broad — it matched the canonical
node/db/rpcdb/ source directory (consolidated in v1.26.28). Previous PRs
needed `git add -f` to land files there. No code references in-repo ./db/
runtime path; runtime DB lives under ~/.lux/ per the canonical operator
convention.
LLM.md + CLAUDE.md updated to reflect actual current main tag.
Anchor /lux + /luxd binary patterns at repo root so the gitignore
rule doesn't accidentally match every directory called "lux" deep
in the tree (which was excluding vms/components/lux that the
previous commit tried to land).
Add the actual UTXO type tree files so v1.26.5 ships with the
package contents external consumers (liquidity/network-bootstrap
etc) need.
