feat(cli): stream plain ktx ingest progress to stderr (KLO-726) (#251)

* feat(cli): share public ingest progress adapter

* feat(cli): stream plain public ingest progress

* test(cli): update plain ingest progress assertions

* chore(cli): satisfy plain ingest progress checks

* fix(artifacts): expect plain ingest stderr progress in installed-CLI smoke

* ci(coverage): make Codecov upload non-fatal and fix repo slug

The Coverage job failed because the Codecov upload returned
'Repository not found' while fail_ci_if_error was true, turning a
Codecov-side issue into a hard CI failure even though all tests pass.

- Set fail_ci_if_error: false on both uploads so Codecov outages or an
  unlinked repo no longer break CI (upload stays best-effort).
- Correct the stale slug Kaelio/ktx -> Kaelio/ktx-ai-data-agents-context
  to match the actual GitHub repo (aligns with main).

* fix(cli): isolate query-history failure capture from scan output

The plain public-ingest progress path passes one captured IO as the
target-level `io`. With progress deps set, both the schema scan and the
query-history ingest resolved their capture to that same shared buffer,
so a non-actionable query-history failure surfaced leftover scan report
text (e.g. "Mode: enriched") as the skipped-facet detail instead of the
real query-history message.

Give the query-history ingest a phase-local capture while preserving the
flow-to-io branch the foreground context-build view relies on.
