MCP server: play Ora et Labora via /api/mcp (#1739)

* docs: design for an MCP server that plays games via direct Postgres access

Proposes a new mcp/ workspace deployed as its own Vercel project: a
streamable-HTTP MCP server (mcp-handler) that replays instance.commands
through hathora-et-labora-game to read state and generate legal moves,
and appends the agent's moves via a new atomic append_command RPC with
seat/turn/legality checks.

* docs: host the MCP server as a route in the existing web app

Adapts the design from a separate mcp/ Vercel project to
web/src/app/api/[transport]/route.ts inside the existing kennerspiel
project: same mcp-handler/tool surface, service-role client added as a
sibling supabase util, middleware matcher excludes the MCP route, and
the engine version-skew risk disappears since the tools share web/'s
hathora-et-labora-game dependency. Doc moves to docs/.

* feat(web): MCP server route for playing games over Postgres

Implements docs/mcp-server-design.md: a streamable-HTTP MCP server at
/api/mcp (mcp-handler + bearer-token auth) exposing list_my_games,
get_game, get_legal_moves, and make_move. State is derived by replaying
instance.commands through hathora-et-labora-game; moves are validated
(seat, turn, reducer legality) and persisted via a new append_command
RPC that compare-and-swaps on the command count. Adds a service-role
supabase client, excludes api/mcp from the session-refresh middleware,
and hand-adds the RPC to supabase.types.ts pending `npm run gentypes`.

Committed with --no-verify: the pre-commit hook runs `next lint --fix`,
which was removed in Next 16 and fails on any commit (pre-existing).
