chore: release v1.5.0 (#67)

* chore: release v1.4.0

* feat: timezone-aware locale formatting

- Add TIMEZONE_TO_REGION map for 50+ timezones worldwide
- Combine app language with timezone region (e.g., en + Europe/Berlin → en-DE)
- Fix times displaying in wrong timezone (treated as UTC instead of local)
- Add parseLocalDateTime() to handle ISO strings without UTC conversion
- Users now get regional formatting (24h time, local date format) regardless of app language
- Swedish user with en-SE locale now gets yyyy-mm-dd format and 24h time
- German user with en-DE locale gets dd.mm.yyyy format and 24h time
- Add missing i18n translation key 'lastSent'
- Update all getSystemLocale() calls to pass app language parameter

* chore: release v1.5.0

* fix: timezone-independent test for CI (use 14:00 instead of 22:00)

* fix: make timezone test independent of server timezone

 - **NEVER release without explicit permission**: Do NOT create tags, releases, or version bumps unless the user explicitly asks for it. Always wait for explicit confirmation before any release action.
+- **NEVER create PRs without explicit permission**: Do NOT create Pull Requests, push branches, or merge code unless the user explicitly asks for it. Always present changes and wait for the user to confirm before any git operations that affect the remote repository.

+### Release Workflow (MANDATORY for minor/major releases)
+
+The `main` branch is protected - releases must go through the automated release script.
+
+**Release Process:**
+```bash
+# 1. Run release script (creates PR, waits for CI, merges, creates tag)
+./scripts/release.sh [patch|minor|major]
+
+# 2. GitHub Actions creates a DRAFT release automatically
+# 3. User asks AI to write release notes:
+#    "Write the release notes for vX.Y.Z"
+# 4. AI writes descriptive release notes following the style guide below
+# 5. User publishes the draft release with the written notes
+```
+
+> ⚠️ **MANDATORY for minor and major releases**: The AI assistant MUST write proper descriptive release notes!
+> Do NOT just publish the auto-generated commit list. Follow the process above.
+
+**AI Assistant Release Notes Workflow:**
+1. When user asks to write release notes for a version:
+   - Check commits since previous tag: `git log vPREV..vNEW --oneline`
+   - Read through the changes to understand what was added/fixed
+   - Write release notes following the style guide below
+   - Present the notes to the user for copying to GitHub
+
 ### Creating Release Notes
 
 > ⚠️ **MANDATORY**: GitHub Releases MUST contain a written message!
 > Not just auto-generated commit lists, but a brief descriptive text.
 
+**Release title:** Use just `vX.Y.Z` (e.g., `v1.4.1`), NOT "Release vX.Y.Z".
+
 **Keep it informative but concise.** Users want to know what changed and where to find it.
