fix: hardcode prod MCP URL instead of ${CEDAR_MCP_URL:-...} templating#4

…lating Testing shows the marketplace sync in Cowork still fails identically after the git-subdir source fix (#3), ruling that out. Next candidate: this file's env-var expansion syntax. Two matching upstream bugs: - anthropics/claude-code#9427: \${VAR} expansion fails specifically for .mcp.json files that live in a plugin root (not a project root) — exactly this file's location. - anthropics/claude-code#40372: \${VAR} expansion fails specifically in the Desktop app, which Cowork runs inside/via. If Cowork's server-side marketplace-content validation can't expand \${CEDAR_MCP_URL:-https://api.mail.cedarcopilot.com/mcp}, it may see a malformed URL and reject the whole plugin's content — surfacing as the same generic "Marketplace sync failed. Check the repository URL and try again." message documented in #61271 for a completely different underlying cause. Trades away the CEDAR_MCP_URL local-dev override on this published repo in favor of Cowork compatibility; local/dev testing needs a separate override until this is confirmed and a lower-risk mechanism is worth revisiting.

Summary
git-subdirsource fix (fix: use explicit git-subdir source for Cowork marketplace-sync compatibility #3, merged) did NOT resolve the Cowork "Marketplace sync failed. Check the repository URL and try again." error — retested live, identical failure..mcp.json'surlfield used env-var expansion syntax (${CEDAR_MCP_URL:-https://api.mail.cedarcopilot.com/mcp}). Two matching upstream bugs:${VAR}expansion fails specifically for.mcp.jsonfiles that live inside a plugin root (not a project root) — exactly this file's location.${VAR}expansion fails specifically in the Desktop app, which Cowork runs inside/via.Fix
Tradeoff
Removes the
CEDAR_MCP_URLlocal-dev override from this published repo — local/dev testing against an ngrok tunnel needs a separate mechanism now. Deliberate, pending confirmation this actually fixes Cowork; revisit a lower-risk override mechanism once confirmed.Test plan
