Ocean run() Reliability & Netlist Regeneration

Fix Ocean SKILL simulation failures after schematic edits. Use when: (1) run() returns nil in <1s with no spectre.out, (2) createNetlist() returns nil, (3) sim results are all nil after changing W/L to design variables, (4) netlist file was deleted or is stale, (5) sim run previously worked but now fails after calling `sim setup` again, (6) OSSHNL-109 error after SKILL edit, (7) library not found / ddGetObj returns nil / Virtuoso started from wrong directory. Covers: the resultsDir binding trap (MOST COMMON), OSSHNL-109 extraction timestamp stale error, stale netlists, sim setup disrupting sessions, direct spectre invocation as bypass, library-not-registered diagnosis, and PSF signal naming.
