On a big codebase the graph showed about 25 boxes of the same weight, with each function's calls in no particular order. This PR makes it readable top to bottom and lets you drill in.

What changes

A function's box lists what it does, in run order

• One numbered row for each call: to its own functions, AWS, a library (SQLite, Redis, …) or HTTP, sorted by line.
• Rows are indented inside loops and ifs, and tagged ↻ (in a loop) or if (only sometimes). Pointing at a row shows its line and the if test.
• Each arrow leaves from its row, and the boxes a function calls are stacked in the same order, so you read down the box and across.
• Calls not drawn are dimmed rows. Clicking one, or Open its calls ›, draws the graph from that function (JavaScript only, as before).
• A box shows at most 6 rows plus "+N more", but never drops a row an arrow leaves from. Calls in a row to one service the same way are one row (SQLite PRAGMA (+3)).

Pointing at a box shows every path through it: up to the entry point and down to what it reaches. Pointing at S3 or a database shows every route there. Clicking a box keeps its paths lit while its code is open. Still CSS only.

Fewer boxes

• 14 functions by default instead of 24. The command now uses the same constant as the analysis, so there's one number.
• When not everything fits, a function that only passes on to one other doesn't get a box; a dashed "via f()" arrow runs past it.
• On graphs of more than 10 functions, boxes leave out docstrings and when pills. Both are in the hover card, which now also says "Called only when …".

Effect

• hermes-agent (404 functions): from 27 dense boxes to 17, each with at most about 7 rows in run order.
• orders-service: lambda_handler() reads 1 read_orders(), 2 check(), 3 save(), 4 announce(), and those boxes stack in that order with no arrows crossing.

Checks

• make check: lint, 42 tests, mkdocs build --strict, package.
• New tests for the rows (order, indents, loop and if tags, merged rows, which row an arrow leaves from, run-order stacking) and for the paths kept in sight.
• One test updated on purpose: run() only passes on to work(), so main() now reaches work() through "via run()".
• Text snapshots are unchanged; the text output still lists calls the old way.
• Screenshots remade; CHANGELOG.md, README.md, docs/usage.md and docs/reading.md updated.
