Add 34 tests covering all previously-untested GuildRepository methods:
invitations/scouts, guild posts, alliances, adventures, treasure
hunts, meals, kill tracking, and edge cases like disband with
alliance cleanup.
Fix test schema setup to apply the 9.2 update schema after init.sql,
which bridges v9.1.0 to v9.2.0 and resolves 9 pre-existing test
failures caused by missing columns (rp_today, created_at, etc.).
Make patch schemas 14 and 19 idempotent so they no longer fail when
applied against a schema that already has the target state (e.g.
festival_color type already renamed, legacy column names).
Per anti-patterns.md item #9, guild-related SQL was scattered across
~15 handler files with no repository abstraction. Following the same
pattern established by CharacterRepository, this centralizes all
guilds, guild_characters, and guild_applications table access into a
single GuildRepository (~30 methods).
guild_model.go and handlers_guild_member.go are trimmed to types and
pure business logic only. All handler files (guild_*, festa, mail,
house, mercenary, rengoku) now call s.server.guildRepo methods
instead of direct DB queries or methods on domain objects.
Add explicit error discards (_ =) for Close() calls on network
connections, SQL rows, and file handles across 28 files. Also add
.golangci.yml with standard linter defaults to match CI configuration.
Re-enable the golangci-lint job in CI (disabled Oct 2025), update to
Go 1.25 and golangci-lint-action v7. Fix errcheck, gosimple S1009,
staticcheck SA4031 and SA2001 errors across 54 files. Remaining ~39
lint errors will be addressed in follow-up commits.
