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
