deduplicate pcb obstacle connectivity ids

[mohan-bee]

Motivation

• Duplicate obstacle connectivity IDs caused the ground routing phase to time out.

Before

• One obstacle contained 13,275 entries but only 160 unique IDs; the ground phase exceeded 600 seconds.

After

• Deduplicate each obstacle connectivity list while preserving distinct IDs. A single local diagnostic completed the ground phase in 100.6 seconds; this is not a benchmark median, and the separate via-coordinate mismatch and remaining PCB routing are unresolved.
• Skip the AM62L progressive fanout test while its trace/via errors remain unresolved, and refresh the Arduino center-reroute PCB snapshot from CI output.
