Sprout v0.0.29 — examples gallery + sort_by

A deliberate change of gear: proving the language, not growing it.

After five straight feature releases, a founder-style review gave the most important advice in the project: "You have enough language. Start proving it by building things. Every awkward pattern found building real projects is worth more than ten new language features."

So v0.0.29 adds no new syntax. It proves Sprout by building real programs with it — and fixes the one thing that genuinely got in the way.

🌱 An examples gallery — real, runnable programs

A new examples/ folder, each file self-contained and commented:

Example	Builds
fizzbuzz	the classic
leaderboard	rank records by score
wordcount	most-common words in text
units	temperature / distance converter
bank	account ledger with overdraft errors
roman	number → Roman numerals
rpn	reverse-Polish calculator (3 4 + 5 *)
todo	a to-do list saved to disk

All eight are now wired into CI, so they can't silently break.

The one earned fix: sort_by(list, task)

Building the leaderboard and word-counter immediately hit a wall — sort only handles a flat list of numbers/text, so "rank these records by a field" was impossible. sort_by orders a list by the value a task returns for each item (stable, in place; reverse() for descending):

make ranked = reverse(sort_by(players, task(p): p["score"]))

That's the whole code change. The other friction found (column padding, fixed-decimal formatting) was deliberately left out — it's workaround-able, and resisting it is the point.
