Declutter the challenge panel and obstacle titles (v4)

Per playtest feedback:
- Drop the per-challenge 'Plays:' line — redundant with the card column and the
  event log (also removes the now-unused chPlays const).
- Drop the 'Attempted by … drag a card … assist' how-to paragraph; players know
  the basics, and the challenge header already names who's challenged.
- Replace the 'Red/Black Obstacle · match to draw' tag with the original card in
  the title (e.g. '5♣ — Loitering Mermaid'), and color the title by suit. The
  left border already marks color; the dead .obstacle-color-tag CSS is removed.

Suit glyphs in the title use plain text symbols (not SUIT_EMOJI) so they take
the theme-aware suit color and stay readable on the dark panel. Verified in
light and dark.

+## Versioning & changelog
+
+The app shows its version number and a player-facing changelog in the ☰ menu → About. Both come from `frontend/src/lib/changelog.js` (rendered by `frontend/src/components/AboutModal.svelte`).
+
+- Bump `VERSION` by one on **every** commit.
+- When a commit changes something players can see, add an entry to the **top** of `CHANGELOG` (`{ version, date, changes: [...] }`) describing it in player-facing terms. Group everything shipping under one version into a single entry.
+- The changelog is for players: skip refactors, tests, tooling, and other internal-only changes. A commit with no user-facing change bumps `VERSION` but adds no entry.
+
 ## Work order
 
 You will be working on tasks in [TODO.md](./TODO.md]. Work on at most two tasks at a time (one is preferable, but two is fine if they dove tail really nicely), and after you finish each task, make a git commit and update the TODO list to check off the completed task.

In the hamburger menu, add an "About" item that pops up a modal with the current version number and a change log. The change log should only cover user-facing changes. Add a note to AGENTS.md about maintaining the change log.

+- [x] **Condense Obstacle card display**: Change how the cards in an Obstacle are laid out. Instead of being one big card and a bunch of little ones under it in a row, they should be a single column, with the cards overlapping so that you can just see the numbers and suits of the previous cards peeking out behind the latest card. This is more compact, puts the focus on the most relevant information, and is in line with the rulebook describing the card layout as a column. This is probably also how the cards in the example play section should be laid out.

-- [ ] **Example Play formatting.** The Example Play section of the Rules page could use a bit more formatting for legibility. Make diagrams of the card state at each step rather than just a text listing. 
 - [ ] **Suggestions.** Take a pass through all of the suggestions in suggestions.js, rewrite ones that are stiff, awkward, or don't fit the theme/setting as described in the rulebook. Move the suggestion pool from suggestions.js into a backend API endpoint.

 ## Security
 
 - [ ] **Defensive coding.** While we trust our players, this app is exposed on the open internet. I'd like to take basic precautions like making sure we're safe against SQL injection (SQLModel should handle this?), doing some basic sanitizing of free inputs from players (valid unicode only + generous character limit should be enough), and making sure that every game action API call is specific and constrained enough that it can't just do arbitrary database updates.
