fmt: README.md files and .cargo/config.toml

Bump the package version to 1.2.1 for multiball Greifarm capture preservation and scoping fixes. Update CHANGELOG.md and refresh the tracked web WASM artifact.

Test Plan:
- `just test` -- passed (152 game tests and 8 service tests)
- `just clippy` -- passed
- `just build-production` -- passed
- `just web-build` -- passed
- `cargo +nightly fmt --all -- --check` -- passed
- `rumdl check --flavor commonmark CHANGELOG.md` -- passed
- `cargo metadata --locked --format-version 1 --no-deps` -- passed
- `git diff --cached --check` -- passed

 ## [Unreleased]
 
+## [1.2.1] - 2026-09-01
+
+### Fixed
+
+- Keep a ball captured by the Greifarm during multiball instead of consuming it;
+  latch the two-ball capture rule at each entry, exclude the launcher release
+  while that capture is active, and let later single-ball re-entries use all
+  four original release choices.
+- Preserve that entry decision through the complete pull phase, scope it to the
+  entering slot until that ball exits the capture zone, and migrate Greifarm
+  state when a held secondary ball becomes the primary ball.
+
+## [1.2.0] - 2026-08-31
+
+### Added
+
+- Seed new SQLite high-score databases that did not exist before opening with
+  the ten distributed demo scores.
+
+### Fixed
+
+- Deliberately diverge from the original game's multiball contact sentinel so a
+  reserve ball that fills a wheel hole leaves it permanently occupied; the
+  surviving ball can no longer enter and score that visibly filled slot again.
+- Match capture-driven multiball collapse timing so the surviving slot keeps
+  double scoring through the current callback, then returns to normal scoring on
+  the next callback and the returning claw remains paused until that collapse;
+  completing the fifth wheel lock still ends multiball scoring immediately.
+- Derive wheel-lock awards from the original live contact words so two balls
+  settling into different slots at once receive the same accumulated award as
+  the original game.
+- Stage an effect-seven reserve-ball request until ball 1's full substep batch
+  has returned, preventing the new slot from participating in collision and
+  capture rules before the original creates it.
+- Bound high-score server resource usage with 1 KiB route body limits,
+  single-operation database concurrency gating, 503 shedding, and offloading
+  SQLite operations to blocking worker threads.
+- Use a relative path for the web build's high-score API endpoint so deployments
+  under nested URL subpaths route requests correctly.
+- Implement bounded exponential backoff with jitter, initial delay and maximum
+  delay bounds, and `Retry-After` header support for failed web high-score
+  submissions.
