pyr0ball 828b69768a refactor: rename ingest → glean throughout codebase
Renames the app/ingest/ package to app/glean/ and updates all
references across Python modules, shell scripts, Vue components,
tests, and documentation.

Intentionally preserved:
- SQLite column name ingest_time (avoids schema migration)
- RetrievedEntry.ingest_time field (maps to the column above)
- Any public-facing JSON keys that reference ingest_time

Changes by category:
- app/ingest/ → app/glean/ (full package move, all parsers)
- app/tasks/ingest_scheduler.py → app/tasks/glean_scheduler.py
- scripts/ingest_corpus.py → scripts/glean_corpus.py
- tests/test_ingest_*.py → tests/test_glean_*.py
- Docstrings, log messages, comments: ingest → glean
- Env var: TURNSTONE_INGEST_INTERVAL → TURNSTONE_GLEAN_INTERVAL
- Shell scripts: glean.log, glean_corpus.py references
- README.md: multi-source ingest → multi-source glean
- .env.example: updated env var name
- patterns/: new diagnostic patterns from 2026-05-20 SSH incident
  (service_crash_loop, pkg_daemon_restart, ssh_forward_conflict)
- SourcesView.vue: pipeline label updated
- All test import paths updated to app.glean.*

285 tests passing.
