* feat: support explicit move colors for handicap games

Add MoveInput enum that accepts both formats:
- Simple: ["D4", "Q16"] - colors inferred from alternation
- Explicit: [["W", "D4"], ["B", "Q16"]] - colors specified directly

This fixes analysis for handicap games where KataGo ignores
initialPlayer for positions with moves and assumes Black-first
alternation. Clients can now send explicit colors to ensure
correct perspective for winrate and territory.

pre-placed on the board.

Release version 1.7.2

fix: health endpoint now checks KataGo process status (#72)

- Health endpoint returns 503 when KataGo process is not alive
- Fixed query_version requests to include required 'id' field
- Fixes keepalive ping error spam in KataGo logs every 30 seconds

The health endpoint previously always returned 200 OK regardless of
whether KataGo was actually running. Now it properly checks the
process_alive flag and returns 503 Service Unavailable when KataGo
has crashed, allowing Salad Cloud liveness probes to trigger restarts.

Release version 1.7.1

Release version 1.6.0

Release version 1.4.6

fix: upgrade KataGo to v1.16.4 for CUDA 12 compatibility (#71)

KataGo v1.15.0 fails to compile with CUDA 12.4 due to stricter
type checking in cudaMalloc (float** to void** conversion error).

KataGo v1.16.4 fixes this issue and maintains human-style model support.

Bump version to 1.7.1 to trigger release.
