fix(gitea-mcp): address MCP tool issues from Sprint 6
Fixes #281 - Multiple MCP tool issues discovered during sprint execution
## Changes
1. **list_issues Token Overflow** (Issue 1)
- Added `milestone` parameter to filter issues server-side
- Reduces response size by filtering at API level instead of client-side
2. **Type Coercion for MCP Serialization** (Issues 2 & 4)
- Added `_coerce_types()` helper function in server.py
- Handles integers passed as strings (milestone_id, issue_number, etc.)
- Handles arrays passed as JSON strings (labels, tags, etc.)
- Applied to all tool calls automatically
3. **Sprint Approval Check Clarification** (Issue 3)
- Updated sprint-start.md to clarify approval is RECOMMENDED, not enforced
- Changed STOP/block language to WARN/suggest language
- Added note explaining this is workflow guidance, not code-enforced
## Files Changed
- mcp-servers/gitea/mcp_server/gitea_client.py: Added milestone param
- mcp-servers/gitea/mcp_server/tools/issues.py: Pass milestone param
- mcp-servers/gitea/mcp_server/server.py: Type coercion + milestone schema
- plugins/projman/commands/sprint-start.md: Clarified approval check
