Bump tools/OpenROAD from 98c6045c72 to 18f08d7ead (current OpenROAD master, 37 merges).

The bot bump PR #4722 is stuck at fa5da1ff84, and both of its CI jobs (pr-head and pr-merge) errored.

Note on the nightly: builds 7690–7692 failed the dashboard QoR check on setup TNS for 10 designs (e.g. asap7/ibex finish TNS −2272 vs. baseline −403, sky130hs/riscv32i −75.8 vs. −19.2). Nightlies 7693/7694 are green, but in 7694 every inline check reported baseline: None / passed=0 failed=0. Nothing was compared, so the green doesn't show that the regression is gone. This PR's QoR check should show where master actually stands.
