fix(ci): improve release workflow

[JasonXuDeveloper]

Summary

Multiple fixes for the release workflow:

1. Fix tag format

• Changed from v1.0.5 to 1.0.5 (existing tags don't have v prefix)
• This was causing the changelog to include ALL commits instead of just since last release

2. Fix bot email for avatar

• Changed to GitHub's bot email format: {APP_ID}+jengine-release-bot[bot]@users.noreply.github.com
• This should make the app avatar show on commits made by the bot

3. Update README with full changelog

• Previously only updated the version number in header
• Now replaces the entire "Latest Features" section with actual changelog content
• Includes both features and bug fixes from the release

Changes

- BASE_TAG="v$CURRENT_CORE"
+ BASE_TAG="$CURRENT_CORE"

- git config user.email "release-bot[bot]@jengine.xgamedev.net"
+ git config user.email "${APP_ID}+jengine-release-bot[bot]@users.noreply.github.com"

# README now gets full feature list, not just version number

Test plan

• Merge and run release workflow
• Verify changelog only includes commits since last release (not all commits)
• Check that bot avatar shows on the release commit
• Confirm README.md and README_zh_cn.md have updated feature lists

Code Review

Found 2 issues related to sed command usage in the workflow.

---

Issue 1: README.md sed command (line 334)

The sed c command with literal newlines in NEW_SECTION will not work as intended. GNU sed interprets the first literal newline as the end of the replacement text, meaning only the first line will be used.

Location:

JEngine/.github/workflows/release.yml

Lines 331 to 335 in 8cb4f3e

	# Replace the entire Latest Features section in README.md
	# Match from "## 🎉 Latest Features" to just before "## 📊 Project Statistics"
	sed -i '/^## 🎉 Latest Features/,/^\[📋 View Complete Changelog\]/c\'"$NEW_SECTION" README.md
	echo "✅ Updated README.md with new features"

The NEW_SECTION variable is constructed using bash newline syntax which creates actual newline characters. For multi-line replacements with sed c command, each line (except the last) must end with a backslash for line continuation.

Suggested fix: Use a temp file approach with the r command instead of c command.

Issue 2: README_zh_cn.md sed command (line 362)

Same issue as above but for the Chinese README file.

Location:

JEngine/.github/workflows/release.yml

Lines 359 to 363 in 8cb4f3e

	NEW_SECTION="## 🎉 最新功能 (v$VERSION)"$'\n'$'\n'"$FEATURES"$'\n'$'\n'"[📋 查看完整更新日志](CHANGE.md)"
	# Replace the entire Latest Features section in README_zh_cn.md
	sed -i '/^## 🎉 最新功能/,/^\[📋 查看完整更新日志\]/c\'"$NEW_SECTION" README_zh_cn.md
	echo "✅ Updated README_zh_cn.md with new features"

Suggested fix: Same temp file approach as Issue 1.
