* test(datasource): cover scoped sync deletions
- deleted connector items remove the matching KB knowledge, scoped per data
source via metadata datasource_id + external_id
- SyncDeletions=false neither deletes nor counts
- stream handler classifies deleted/failed items like the batch loop
* fix(datasource): perform real sync deletions scoped per data source
- applyFetchedItem now performs the KB deletion instead of only counting
- lookup is scoped to datasource_id + external_id so identical external IDs
from two data sources cannot collide or overwrite each other
- ingestItem update-path lookup uses the same scoped query
* fix(datasource): note failed deletions retry only on full sync
- SyncResult.DeletionFailed tracks deletion failures (subset of Failed)
- streaming partial message warns that failed deletions only retry on a full
sync, since the connector cursor is checkpointed past the deleted item
* fix(datasource): humanize deletion errors, keep raw detail in logs
- raw lookup/delete errors go to server logs only, with full context
- UI samples carry a humanized "see server logs" fallback
- add datasource.syncError.* i18n keys
Note: ko-KR / ru-RU syncError translations were generated without a
native-speaker review.
* fix(datasource): hard-delete synced rows and tighten deletion scoping
Sync-internal deletions now call HardDeleteKnowledge after the soft-delete
cascade so tombstones cannot block re-sync; subtree sweeps and URL metadata
attach failures are handled with datasource scoping and explicit errors.
* chore: add git hooks aligned with CI and PR checks
Install via scripts/install-git-hooks.sh (sets core.hooksPath). Pre-commit
runs whitespace/gofmt/golangci-lint on staged files; pre-push mirrors
app/frontend/cli workflows on the diff since origin/main.
* fix: gofmt test file; tighten pre-push to match CI app workflow
Pre-push now gofmts the full PR diff and runs go vet on all app packages
(like app.yml), not only Go files in the latest commit. Previous pushes
skipped checks via --no-verify and because hook-only commits had no .go files.
* fix(hooks): align pre-push diff with GitHub PR base via gh
Use three-dot diff against the open PR baseRefOid (same as CI) instead of
a two-dot merge-base range; run full go vet on every push with Go PR changes.
* style: gofumpt datasource_service_test.go
