- Add Rank=1..13 explicit discriminants so `rank as u8 == rank.value()`; collapse 13-arm value() match to `self as u8`
- Add Rank::RANKS and Suit::SUITS iteration constants
- Add Rank::checked_add / checked_sub (const fn, type-safe boundary enforcement); update rules.rs to use them
- Add GameState::possible_instructions() enumerating all valid move_cards triples (foundation for hints/solver)
- Fix waste buffer card peeking through during draw-slide animation by setting Visibility::Hidden on the buffer entity in sync_cards

- Hoist APP_DIR_NAME = "ferrous_solitaire" to solitaire_data crate root
as pub(crate); remove 5 duplicate local definitions across achievements,
progress, settings, storage, replay modules (L-9)
- Add #[must_use] to can_place_on_foundation, can_place_on_tableau, and
is_valid_tableau_sequence in solitaire_core::rules so callers that
accidentally discard the result get a compile-time warning (L-6)

move_cards only checked that the *bottom* card of a moved stack landed
legally on the destination — the cards above the bottom went through
unverified. A player could lift an arbitrary selection from one column
and drop it on another whenever the bottom happened to match, even if
the upper cards didn't form a descending alternating-colour sequence.
Adds is_valid_tableau_sequence(&[Card]) -> bool to rules.rs (4 lines)
and one call site in move_cards's tableau-destination branch. One
focused test covering single-card / valid-run / same-colour /
rank-gap cases.
Reported by Quat: "stack 4 onto stack 2" was accepted when illegal.

Standard Klondike behaviour: any Ace can land in any empty foundation,
and that slot then claims the suit until the pile empties. The
previous PileType::Foundation(Suit) variant pre-assigned each of the
four foundations to a fixed suit ("C / D / H / S" placeholders) and
rejected mismatched Aces — non-standard and (per the smoke-test
feedback) confusing.
Replaces the variant payload with a slot index Foundation(u8) (0..=3)
and derives the claimed suit from the bottom card via a new
Pile::claimed_suit() method. The bottom card is, by construction,
the Ace that established the claim; using it directly eliminates an
entire class of "stuck claim after undo" bugs that a separate
claimed_suit field would have introduced.
can_place_on_foundation drops its suit parameter — the rule reduces
to "empty pile accepts any Ace; non-empty pile accepts the next
rank up of the bottom card's suit." Iteration sites across
input_plugin, cursor_plugin, selection_plugin, card_plugin,
auto_complete_plugin, game_plugin, layout, and hud_plugin all swap
the four-suit list for `(0..4u8).map(PileType::Foundation)`.
next_auto_complete_move now prefers a slot whose claimed_suit matches
the candidate card before falling back to the first empty slot for
an Ace — so the same suit consistently auto-targets the same slot
across the whole game, matching player expectations.
The HUD selection label and the hint toast read claimed_suit() and
fall back to "Foundation N" / "move to foundation" only when the
slot is empty. Empty foundation pile markers no longer render the
suit-letter children — they're plain translucent rectangles, matching
empty tableau placeholders.
Save-format invalidation: GameState gains a schema_version field
(serde-default to 1 for back-compat parsing of old files), the
constant is bumped to 2, and load_game_state_from rejects mismatched
schemas. Old in-progress saves silently fall through to "fresh game
on launch" — the user accepted this loss given the mechanic change.
Stats / progress / achievements / settings live in separate files,
contain no PileType data, and are unaffected.
9 new tests pin the contract:
- Pile::claimed_suit returns None for empty / non-foundation, Some
for non-empty foundation
- Any Ace lands in the first empty foundation; successive Aces
distribute across slots 0..3
- Claim drops when the slot is emptied via undo
- Auto-complete picks the slot with a matching claim, not the first
empty slot
- A v1-format game_state.json is rejected; sibling stats save/load
is unaffected

Task #27: Double-click auto-move — best_destination() finds optimal target
(foundation over tableau); handle_double_click() fires MoveRequestEvent.
Task #28: Hint system — find_hint() returns first legal from/to/count triple;
H key tints the source stack HintHighlight (yellow pulse via tick_hint_highlight).
Task #29: No-moves detection — has_legal_moves() checks stock/waste/all face-up
cards; check_no_moves system fires InfoToastEvent("No moves available") once per
stalemate (debounced so it fires only once until the state changes).
Task #30: Forfeit — G key fires ForfeitEvent; StatsPlugin records abandoned game,
persists stats, starts a new deal.
Task #37: Mute-all (M) and mute-music (Shift+M) toggles; MuteState resource
applied in apply_volume_on_change.
Task #39: Daily challenge HUD constraint label (time limit / target score).
Task #40: Undo-count HUD label; amber colour when undos > 0.
Task #44: Win-streak and level line on pause screen.
Task #48: Undo sound routes UndoRequestEvent → lib.flip audio channel.
Task #49: Onboarding banner rich-text key highlights — D and H rendered as
orange KeyHighlightSpan children so they stand out from body text.
Also registers CursorPlugin in solitaire_app (tasks #31/#32 wire-up).

- King-on-Queen foundation completion (the end-game move had no test)
- King wrong-suit rejected on completed foundation
- Ace-on-Two valid placement (Ace.value()+1 == Two.value(), different color)
- Same-rank different-color invalid (rank difference is 0, not 1)
