fix(cli): timeline tag width, test env isolation, and logging verbosity

Miscellaneous fixes across CLI and core modules:

- Timeline: widen TAG_WIDTH from 10 to 11 to accommodate longer event
  type labels without truncation
- render.rs: save and restore LORE_ICONS env var in glyph_mode test to
  prevent interference from the test environment leaking into or from
  other tests that set LORE_ICONS
- logging.rs: adjust verbose=1 to info level (was debug), verbose=2 to
  debug — this reduces noise at -v while keeping -vv as the full debug
  experience
- issues.rs, merge_requests.rs: use infodebug! macro consistently for
  ingestion summary logging
