feat: add comprehensive JOSS paper draft

Add complete Journal of Open Source Software (JOSS) submission package:

- paper.md: Complete JOSS paper with all required sections
  - Summary of ObjectState framework and dual-axis inheritance
  - Statement of need for scientific computing workflows
  - Comprehensive state of the field analysis
  - Implementation details and quality assurance metrics
  - Working code example demonstrating key features
  - Research applications and future directions

- paper.bib: Complete bibliography with 28 citations
  - Software engineering best practices
  - Existing configuration frameworks
  - Python Enhancement Proposals
  - Design patterns and revision control systems

- JOSS_SUBMISSION_NOTES.md: Submission guidance
  - Pre-submission checklist
  - Author ORCID update instructions

The paper rigorously documents ObjectState's novel dual-axis inheritance
model (context hierarchy + class inheritance), integrated state management
with git-like undo/redo, and zero-dependency pure-stdlib implementation.

Ready for author review and ORCID update before submission.

+# JOSS Submission Notes for ObjectState
+
+This document provides guidance for preparing and submitting the ObjectState paper to the Journal of Open Source Software (JOSS).
+
+## Files Created
+
+1. **paper.md** - The main JOSS paper in markdown format
+2. **paper.bib** - Bibliography with all references cited in the paper
+3. **JOSS_SUBMISSION_NOTES.md** - This file with submission guidance
+
+## Before Submitting
+
+### 1. Update Author Information
+
+**CRITICAL**: Replace the placeholder ORCID in `paper.md`:
+
+```yaml
+authors:
+  - name: Tristan Simas
+    orcid: 0000-0000-0000-0000  # TODO: Replace with actual ORCID
+```
+
+- Get your ORCID at [https://orcid.org/](https://orcid.org/)
+- Update line 13 of `paper.md` with your actual ORCID number
+- If there are co-authors, add them to the authors section
+
+### 2. Verify Repository Requirements
+
+JOSS requires that your repository meets these criteria:
+
+- ✅ **Open source license**: MIT license present in LICENSE file
+- ✅ **Version control**: Git repository on GitHub
+- ✅ **Documentation**: ReadTheDocs documentation available
+- ✅ **Installation instructions**: Present in README.md
+- ⚠️ **Tagged release**: Ensure you have a tagged release (e.g., v0.1.0)
+- ⚠️ **Community guidelines**: Consider adding CONTRIBUTING.md if not present
+- ✅ **Tests**: Comprehensive test suite with 100% coverage
+- ⚠️ **Statement of need**: Included in paper.md
+
+### 3. Create a Tagged Release
+
+Before submitting to JOSS, create a release on GitHub:
+
+```bash
+git tag -a v0.1.0 -m "Initial JOSS submission"
+git push origin v0.1.0
+```
+
+Or use GitHub's web interface to create a release.
+
+### 4. Review Paper Content
+
+The paper includes:
+
+- **Summary**: Overview of ObjectState and its novel dual-axis inheritance model
+- **Statement of Need**: Explains why this software is needed and who the target audience is
+- **State of the Field**: Compares to existing configuration frameworks
+- **Implementation & Quality**: Details architecture, components, and quality assurance
+- **Example Usage**: Code example demonstrating dual-axis inheritance
+- **Research Applications**: Use cases in scientific computing
+- **Future Directions**: Planned enhancements
+
+### 5. Check References
+
+All references in `paper.bib` should be accurate and complete. Key reference categories:
+
+- Software engineering best practices (Wilson, Jiménez, Martin, etc.)
+- Existing configuration frameworks (Hydra, OmegaConf, pydantic-settings, etc.)
+- Python Enhancement Proposals (PEP 557, PEP 567, PEP 484, etc.)
+- Design patterns and architecture (Gamma, Fowler, etc.)
+
+### 6. Verify Paper Metadata
+
+Check the YAML frontmatter in `paper.md`:
+
+```yaml
+title: Complete and descriptive title ✅
+tags: Relevant keywords ✅
+authors: Name, ORCID, affiliation ⚠️ (Update ORCID)
+affiliations: Institution details ✅
+date: Submission date ✅
+bibliography: paper.bib ✅
+repository-code: GitHub URL ✅
+url: Documentation URL ✅
+```
+
+## JOSS Submission Process
+
+1. **Pre-submission inquiry** (Optional but recommended):
+   - Open an issue at [https://github.com/openjournals/joss-reviews/issues](https://github.com/openjournals/joss-reviews/issues)

+   - Get feedback before formal submission
+
+2. **Formal submission**:
+   - Go to [https://joss.theoj.org/papers/new](https://joss.theoj.org/papers/new)
+   - Provide repository URL: `https://github.com/trissim/objectstate`
+   - The JOSS bot will validate your submission
+   - Fix any issues flagged by the bot
+
+3. **Review process**:
+   - Editor assigns reviewers
+   - Reviewers evaluate software quality, documentation, and paper
+   - Address reviewer comments by updating code/docs/paper
+   - Typical review takes 4-8 weeks

+docker run --rm -v $(pwd):/data openjournals/paperdraft
+
+# 3. Or use the whedon gem (requires Ruby)
+gem install whedon
+whedon prepare --paper paper.md
+
+# 4. Check that tests pass
+pytest
+
+# 5. Verify documentation builds
+cd docs && make html
