Release v1.0.0: Mark expressql as Production/Stable

[Copilot]

Mark expressql as production-ready with v1.0.0, establishing API stability commitment. Package has zero open issues, comprehensive test coverage across Python 3.8-3.14, and full Sphinx documentation.

Version & Metadata

• pyproject.toml: Bump version 0.3.9 → 1.0.0, classifier Beta → Production/Stable
• docs/source/conf.py: Update version 0.3.7 → 1.0.0

Documentation Updates

README.md

• Python Support: Added explicit statement about Python 3.8-3.14 support with CI coverage
• Ecosystem Section: New section positioning expressql within SQL toolkit:
  • expressql: Expression/condition DSL (this package)
  • recordsQL: DML query builder (SELECT, INSERT, UPDATE, DELETE, JOIN, WITH)
  • tablesQLite: DDL schema management (CREATE TABLE, ALTER TABLE, migrations)
• FAQ: Expanded to explain modular architecture and integration patterns
• Roadmap: Refined goals, removed deprecated items (full query builder now separate package)

CHANGELOG.md

• Added v1.0.0 release entry documenting stable release, ecosystem links, and production readiness

Testing

All 173 existing tests pass. No code changes—metadata and documentation only.

Original prompt

Objective

Prepare expressql for the 1.0.0 stable release by updating version numbers, documentation, and project metadata to reflect production-ready status.

Changes Required

1. Update pyproject.toml

• Bump version from 0.3.9 to 1.0.0
• Change classifier from "Development Status :: 4 - Beta" to "Development Status :: 5 - Production/Stable"
• Verify Python version classifiers include 3.8 through 3.14 (should already be present)

2. Update docs/source/conf.py

• Update release = '1.0.0' (currently shows 0.3.7)
• Update version = '1.0.0' (currently shows 0.3.7)

3. Update README.md

Add Python version support statement

After the introductory paragraph, add:

**Supports Python 3.8 through 3.14** with comprehensive test coverage across all versions.

Add Ecosystem section

Add this new section after the Features section and before the Quick Example:

---

## 🔗 Ecosystem

**expressql** is part of a complete SQL toolkit for Python:

- **expressql** (this package) - Build SQL expressions and conditions with safe, intuitive syntax
- **[recordsQL](https://github.com/Grayjou/recordsQL)** - Full query builder for DML operations (SELECT, INSERT, UPDATE, DELETE, JOIN, WITH)
- **[tablesQLite](https://github.com/Grayjou/tablesQLite)** - SQLite schema management and DDL operations (CREATE TABLE, ALTER TABLE, migrations)

Use them independently or together for a complete, type-safe SQL solution.

---

Update FAQ section

Replace the first FAQ question "Why doesn't expressql include full query builders?" with:

**Why doesn't expressql include full query builders?**  
expressql focuses specifically on expressions and conditions - the building blocks of SQL queries. For complete query building: 
- Use **[recordsQL](https://pypi.org/project/recordsql/)** for DML operations (SELECT, INSERT, UPDATE, DELETE)
- Use **[tablesQLite](https://pypi.org/project/tablesqlite/)** for DDL operations (CREATE TABLE, schema management)

This modular approach lets you use only what you need, or combine all three for a complete SQL solution.

Update Roadmap section

Replace the current roadmap with:

## Roadmap

- 🌌 More built-in SQL functions (`expressql.functions`)
- 🌌 Chain-aware logical optimizations
- 🌌 Better error tracing and SQL preview options
- 🌌 Performance optimizations for complex expression trees

4. Create/Update CHANGELOG.md
