Oracle round-9 watch-out: same liveMeta.fetchedFrom leak class
existed in two more user-visible surfaces:
- src/components/Telemetry.tsx: 'source' block rendered the host
string. Now hard-coded 'EA2'.
- src/scenes/Landing.tsx: hero paragraph said 'runs end-to-end
through EA2 on <host>'. Dropped the host suffix entirely.
liveMeta import removed from Telemetry (no other refs). Landing
still uses liveMeta for the workItems/distinctDefs stat counters.
