fix(data): resolve 8 GPU cross-source near-duplicates and spec conflicts

Merge 8 confirmed cross-source GPU duplicate pairs where the same physical
product was imported twice under different slug conventions (one from the
Kaggle bulk dataset, one from TechPowerUp/vendor). Kept the more complete /
correctly-sourced side, source-verified every field where the two disagreed,
unioned source_urls, and deleted the redundant file (2076 -> 2068).

Pairs merged (keep <- delete):
- instinct-mi210 <- radeon-instinct-mi210 (same CDNA2 die, 6656 SP / 64 GB
  HBM2e / 300 W; kept AMD+TPU-sourced 2022-03-22 launch record)
- instinct-mi325x <- radeon-instinct-mi325x (kept 256 GB HBM3e / 6 TB/s per
  AMD official spec; dropped the 288 GB Kaggle value, which is wrong)
- geforce-rtx-3060-8-gb <- geforce-rtx-3060-8gb (kept the correct 2022-10-12
  launch record; the other listed a wrong 2023-05-25 date)
- geforce-rtx-5060-ti-16-gb <- geforce-rtx-5060-ti (kept base_clock 2407 MHz
  per NVIDIA official 2.41 GHz; dropped the 2250 MHz side)
- radeon-rx-9060-xt-16-gb <- radeon-rx-9060-xt (kept the 16 GB record)
- tesla-p100-pcie-16-gb <- p100-pcie-16gb (kept the canonical Tesla-named
  record; folded timespy_score)
- v100-pcie-16gb <- tesla-v100-pcie-16-gb (kept TDP 250 W; V100 PCIe is 250 W
  per NVIDIA, the other side's 300 W is wrong)
- v100-sxm2-32gb <- tesla-v100-sxm2-32-gb (kept TDP 300 W; V100 SXM2 is 300 W
  per NVIDIA; corrected fp32 16.35 -> 15.7 TFLOPS per NVIDIA V100 datasheet)

Close-variant families that merely share a name prefix (Tesla K40 d/m/s/t,
GRID vGPU profiles, PCI/AGP and MXM/PCIe bus variants, OEM SKUs) were left
unmerged: they are distinct real products, not duplicates.

Sources: AMD Instinct MI325X datasheet (256 GB HBM3e / 6 TB/s); NVIDIA
GeForce RTX 5060 family spec page (base 2.41 GHz / boost 2.57 GHz); NVIDIA
Tesla V100 datasheet and product brief (PCIe 250 W, SXM2 300 W, FP32 15.7
TFLOPS).
