Show the build, play from the keyboard, and clean up the ledger

Five things from the second playtest.

A status line at the top of every screen: the game, the pack, your current
title, and the version plus the commit it came from. `tools/stamp.js` writes the
commit into src/build-info.js before serving and before building, so a
distributed dist/theladder.html states exactly which commit produced it. An
uncommitted working tree gets a `+` suffix — "4cab9fc+" is honest in a way a
bare SHA would not be.

The whole game is now playable on Enter. Every screen marks one control and the
app focuses it after each render: the first *available* option while choosing,
the next-turn button once the result is in, "keep going" on the retrospective.
Tab and Shift+Tab reach the other options. Locked options needed no special
handling — the browser's tab order already skips disabled controls, so they stay
visible without being in the way.

"What is notable? under What changed?" — two fixes. `notable` is the
retrospective's own list of moments; a display rule can now say
`inLedger: false` and it is left out, because "Notable — changed" tells nobody
anything. Flags are the opposite and stay, but as sentences the pack supplies
rather than as booleans: "The envelope is in your locker." instead of "the
envelope: now true".

Exported logs live in logs/, gitignored, and `npm run analyze` reads the newest
one there when given no argument. A log records what a real person did turn by
turn, including whatever they typed into the feedback box — committing one once
would put it in the history for good.

Version set to 0.3.0 on the reasoning that the engine was 0.1 and the interface
0.2; say if you want a different scheme and I will renumber.

119 tests. Reasoning in docs/DECISIONS.md §25-28.
