feat: add the organization profile README

Mirrors the site at fetiai.github.io in the content and order GitHub can render,
so moving between the two surfaces is never disorienting.

It lives at profile/README.md rather than the repository root, because only that
path is surfaced on the organization page -- a root README describes the
repository instead, which looks correct in the repo and blank where it matters.

Each thumbnail is an animated WebP wrapped in a link to that project's live demo,
so the most eye-catching element on the page is also its primary call to action.
WebP carries more quality per byte than GIF here: both are 720px wide against the
480px the GIFs managed, and both came out smaller.

Image sources are absolute raw URLs. Relative paths resolve against the file when
the README is viewed in the repository but against the repository root when it is
rendered on the organization page, so one of the two views would break; absolute
URLs work in both.

Every accuracy in the results table is read against the 0.9248 constant-predictor
baseline, which is why the baseline is a row in that table rather than a footnote,
and phishing recall leads the columns -- it is the number that actually moves.

+## Magic Cube Solver
+

+
+Six search algorithms racing a 5×5×5 diagonal magic cube — replayed move by move.
+
+A 5×5×5 diagonal magic cube has 125 cells that must be a permutation of 1..125,
+with all 109 rows, columns, pillars and diagonals summing to 315. Six local-search
+and metaheuristic algorithms attack it server-side in Go, and the browser replays
+the resulting swap log on a scrubber against a live objective-value plot.
+
+The Genetic Algorithm is the exception. Being a population method it has no single
+sequence of swaps, so it returns no trajectory — the interface charts it rather than
+animating it.

+## PhishGuard
+
+[![PhishGuard classifying a URL](https://raw.githubusercontent.com/fetiai/.github/master/profile/assets/phishguard.webp)](https://phiusiil.faizath.com)
+
+Phishing URL classifier — KNN and Naive Bayes, each written twice.
+
+Trained on the UCI PhiUSIIL dataset: 140,404 URLs, 49 features, 7.5% phishing.
+The pipeline runs EDA, missing-value handling, outlier treatment, feature
+engineering, scaling and SMOTE. KNN and Gaussian Naive Bayes are each implemented
+from scratch and with scikit-learn, so the pair can be compared directly.
+
+Dataset: [UCI PhiUSIIL Phishing URL Dataset](https://archive.ics.uci.edu/dataset/967/phiusiil+phishing+url+dataset)
+(repository ID 967). Class 0 is phishing and is the positive class throughout.
+
+**Algorithms**
+
+`K-Nearest Neighbors (from scratch)` · `K-Nearest Neighbors (scikit-learn)` ·
+`Gaussian Naive Bayes (from scratch)` · `Gaussian Naive Bayes (scikit-learn)` ·
+`EDA` · `Feature Engineering` · `SMOTE`
+
+**Results** — measured on a 28,081-row validation split.
+
+| Model | Phishing recall | Accuracy | F1 |
+|---|---|---|---|
+| KNN (from scratch) | 0.759 | 0.9805 | 0.856 |
+| KNN (scikit-learn) | 0.763 | 0.9807 | 0.859 |
+| Gaussian NB (from scratch) | 0.788 | 0.9779 | 0.845 |
+| Gaussian NB (scikit-learn) | 0.888 | 0.9819 | 0.883 |
+| **Baseline — constant "legitimate"** | **0.000** | **0.9248** | **—** |
+
+Read every accuracy against that 0.9248 baseline. The corpus is 92.48% legitimate, so
+answering "legitimate" to everything scores 0.9248 while catching no phishing at all —
+which is why phishing recall, not accuracy, is the number that actually moves. The
+held-out file shipped with the dataset has no labels, so there is no test score and
+none is claimed.
