fix: replace YAML-conflicting markdown separators in release workflow

Changed Markdown horizontal rules from "---" to "___" in heredoc content
to prevent YAML parser conflicts. The "---" string at the start of a line
is a YAML document separator which causes parsing issues even inside bash
heredocs within GitHub Actions workflows.

Root cause:
- Lines 151 and 226 contained "---" Markdown horizontal rules
- YAML parsers interpret "---" as document separators
- This prevented workflow jobs from executing (no jobs scheduled)
- Changed to "___" which creates identical Markdown output

Impact:
- Fixes workflow run 18804889309 where no jobs executed
- Fixes workflow run 18804651253 with same issue
- Both "___" and "---" render as horizontal rules in Markdown
- Workflow should now properly detect version changes and execute all jobs

-### 🐛 Bug Fixes
-
-**Issue #228: Fix Docker Port Configuration Mismatch**
-
-Fixed critical Docker configuration bug where custom PORT environment variable values were not properly mapped to container ports, causing connection failures in Docker deployments.
-
-#### Problem
-- **docker-compose.yml**: Port mapping `"${PORT:-3000}:3000"` hardcoded container port to 3000
-- **docker-compose.yml**: Health check hardcoded to port 3000
-- **Dockerfile**: Health check hardcoded to port 3000
-- Impact: When PORT≠3000 (e.g., PORT=8080), Docker mapped host port to wrong container port
-
-#### Solution
-- **docker-compose.yml line 44**: Changed port mapping to `"${PORT:-3000}:${PORT:-3000}"`
-- **docker-compose.yml line 56**: Updated health check to use dynamic port `$${PORT:-3000}`
-- **Dockerfile line 93**: Updated HEALTHCHECK to use dynamic port `${PORT:-3000}`
-- **Dockerfile line 85**: Added clarifying comment about PORT configurability
-
-#### Testing
-- Verified with default PORT (3000)
-- Verified with custom PORT (8080)
-- Health checks work correctly in both scenarios
-
-#### Related Issues
-- Fixes #228 (Docker Compose port error)
-- Likely fixes #109 (Configuration ignored in HTTP mode)
-- Likely fixes #84 (Can't access container)
