Add R, SQL and reproducible-analysis skills

Backed by the /alertt-data/ pipeline: R (tidyverse, ggplot2), SQL (schema
design, joins, window functions), SQLite, Quarto, renv/git.

Scoped deliberately to descriptive analysis. No modelling or inference claims,
because the project does not contain any.
