NVAP v0.1.8 — Single-soma cells and cleaner segmentation

The colored microglia view now shows only components eligible for cell analysis. Both paths use the same single-soma quality check, so unsupported fragments and ambiguous components with multiple supported soma cores are excluded from the display, cell counts, and per-cell exports. The current green threshold and slice trim apply to eligibility; each accepted cell keeps its full visible arbor.

Large microscopy stacks now retain soma-thickness validation on a bounded grid instead of bypassing it. Faint branch connections are resolved before adding missed-cell markers, reducing unnecessary color boundaries. Background padding also prevents edge branches from receiving artificial soma-sized radii.

On the reviewed cortex sample, the shared eligibility check retained 115 of 188 candidate components and excluded 73. These are application quality thresholds, not a validated biological cell classification; the criteria are documented in HOW_IT_WORKS.md.

Validation: 238 unit tests passed in each of the CPU and DirectML environments, including shared display/analysis eligibility, soma-free and multi-soma rejection, large-stack checks, and dense/sparse display caches. Integration checks: 13 passed, 3 skipped. Packaged executables are checked against the release source and smoke-tested before publication.
