docs(module-b): add GSoC 2026 final-evaluation blog

[manshusainishab]

The GSoC 2026 final-evaluation blog for Module B (Noise / Relevance Filter), committed alongside the mid-evaluation blog (#1004).

A first-person write-up of the second half of the project — turning the mid-eval classifier into a real pipeline stage and integrating it with three modules being built in parallel: the DB hand-off (#989), the Postgres-only migration bug (#988), committing the cross-module contracts (#1019), the B↔C "a label is a hint, not a gate" decision (Module C now reads both labels, a135742), the row-lock issue I raised (#1025 → #1030), and the infrastructure-failure retry policy (#1034). Closes on the final metrics (#1035): 93% agreement, recall 1.000, 0 knowledge lost.

.gitignore gets one ! negation (same pattern as the mid-eval blog). Docs-only. A version of this post is also published on Medium for the GSoC submission.

Estimated code review effort: 1 (Trivial) | ~5 minutes

Merge Risk: 🔵 Low · up to 40701

The PR adds the final-evaluation documentation and does not introduce runtime behavior changes. It is mergeable with owner awareness that the evaluation table should explicitly map KEEP and DROP to the production KNOWLEDGE and NOISE labels to avoid reader confusion.
