Add Welly Toss: the playable page and its place in the catalogue, on the rules in `welly-toss/throw.js` #334

Welly Toss now has its playable page at /welly-toss/ and its place in the catalogue, on the rules in welly-toss/throw.js. The page drives the game only through those rules.

Tested before pushing:

• Passing: welly-toss (the 4 new page tests plus the rules tests), serve.test.mjs, shell.test.mjs, town.test.mjs, and the welly-toss cases in playtest.test.mjs, including its scripted round.
• Not run: the full bun test, the playtest per-game budget check, bun scripts/design-lint.ts and bun scripts/gate.ts (neither script exists in this clone).
• bun x tsc --noEmit printed the compiler help text instead of a type-check result, so treat it as unchecked.
• The page was never opened in a browser. I viewed the share card only, which shows the field, flags, side lines, windsock and thrower. The flight, HUD and live region were exercised through the playtest harness.

The page (welly-toss/index.html):

• It draws the field in the engine's fixed 30° camera on the 360x280 canvas, with mown stripes, white side lines, chalk lines and a pole and pennant at each flag. A windsock shows this throw's crosswind.
• The thrower swings the boot on its arc and the flight follows. A chalk or red mark stays where each throw landed.
• Tap, click, Space or Enter releases the boot, and a release after the last throw starts a new contest.
• The HUD shows the throw number, each distance or foul, the best-three total, a saved best total and the wind. Each release, landing and the final result goes through an aria-live region.
• Pennants and the windsock flutter at 8 fps, and that stops under prefers-reduced-motion.
• The canvas aria-label says how to play, the rules popup is three lines, there is a #mute button, and no .mp3 is committed.

Catalogue:

• shell.js has the exact GAMES entry from the issue.
• The root index.html has the matching <li>.
• The README has a Games row, a place in the no-music list and an ambient-motion mention.
• bun scripts/og.mjs has been run, adding og/welly-toss.png and updating og/home.png.

Tests:

• rounds.mjs has a scripted round. It lets go at the tick the rules' own fly says lands furthest in that throw's wind, and it reaches the end line.
• serve.test.mjs asserts that /welly-toss/ and /welly-toss/throw.js answer 200.
• welly-toss/page.test.mjs is new.

Not done: no rule of its own and no dependencies. Only the head of the shell's town-building list changes through the GAMES entry. There was nothing to rebase onto, since the branch was already up to date with origin/main.

To try it, run bun serve.mjs and open /welly-toss/, or use this pull's preview.
