docs: Fix ADR numbering conflicts and create comprehensive documentation indices

This commit resolves all documentation issues identified in the comprehensive review:

CRITICAL FIXES:
- Renumbered duplicate ADRs to eliminate conflicts:
  * ADR-022-migration-race-condition-fix → ADR-037
  * ADR-022-syndication-formats → ADR-038
  * ADR-023-microformats2-compliance → ADR-040
  * ADR-027-versioning-strategy-for-authorization-removal → ADR-042
  * ADR-030-CORRECTED-indieauth-endpoint-discovery → ADR-043
  * ADR-031-endpoint-discovery-implementation → ADR-044

- Updated all cross-references to renumbered ADRs in:
  * docs/projectplan/ROADMAP.md
  * docs/reports/v1.0.0-rc.5-migration-race-condition-implementation.md
  * docs/reports/2025-11-24-endpoint-discovery-analysis.md
  * docs/decisions/ADR-043-CORRECTED-indieauth-endpoint-discovery.md
  * docs/decisions/ADR-044-endpoint-discovery-implementation.md

- Updated README.md version from 1.0.0 to 1.1.0
- Tracked ADR-021-indieauth-provider-strategy.md in git

DOCUMENTATION IMPROVEMENTS:
- Created comprehensive INDEX.md files for all docs/ subdirectories:
  * docs/architecture/INDEX.md (28 documents indexed)
  * docs/decisions/INDEX.md (55 ADRs indexed with topical grouping)
  * docs/design/INDEX.md (phase plans and feature designs)
  * docs/standards/INDEX.md (9 standards with compliance checklist)
  * docs/reports/INDEX.md (57 implementation reports)
  * docs/deployment/INDEX.md (deployment guides)
  * docs/examples/INDEX.md (code samples and usage patterns)
  * docs/migration/INDEX.md (version migration guides)
  * docs/releases/INDEX.md (release documentation)
  * docs/reviews/INDEX.md (architectural reviews)
  * docs/security/INDEX.md (security documentation)

- Updated CLAUDE.md with complete folder descriptions including:
  * docs/migration/
  * docs/releases/
  * docs/security/

VERIFICATION:
- All ADR numbers now sequential and unique (50 total ADRs)
- No duplicate ADR numbers remain
- All cross-references updated and verified
- Documentation structure consistent and well-organized

These changes improve documentation discoverability, maintainability, and
ensure proper version tracking. All index files follow consistent format
with clear navigation guidance.

+# ADR-023: Strict Microformats2 Compliance
+
+## Status
+Proposed
+
+## Context
+StarPunk currently implements basic microformats2 markup:
+- h-entry on note articles
+- e-content for note content
+- dt-published for timestamps
+- u-url for permalinks
+
+"Strict" microformats2 compliance would add comprehensive markup for full IndieWeb interoperability, enabling better parsing by readers, Webmention receivers, and IndieWeb tools.
+
+## Decision
+Enhance existing templates with complete microformats2 vocabulary, focusing on h-entry, h-card, and h-feed structures.
+
+## Rationale
+1. **Core IndieWeb Requirement**: Microformats2 is fundamental to IndieWeb data exchange
+2. **Template-Only Changes**: No backend modifications required
+3. **Progressive Enhancement**: Adds semantic value without breaking existing functionality
+4. **Standards Maturity**: Microformats2 spec is stable and well-documented
+5. **Testing Tools Available**: Validators exist for compliance verification
+
+## Consequences
+### Positive
+- Full IndieWeb parser compatibility
+- Better social reader integration
+- Improved SEO through semantic markup
+- Enables future Webmention support (v1.3.0)
+
+### Negative
+- More complex HTML templates
+- Careful CSS selector management needed
+- Testing requires microformats2 parser
+
+## Alternatives Considered
+1. **Minimal Compliance**: Current state - rejected as incomplete for IndieWeb tools
+2. **Microdata/RDFa**: Not IndieWeb standard, adds complexity
+3. **JSON-LD**: Additional complexity, not IndieWeb native
+
+## Implementation Scope
+### Required Markup
+1. **h-entry** (complete):
+   - p-name (title extraction)
+   - p-summary (excerpt)
+   - p-category (when tags added)
+   - p-author with embedded h-card
+
+2. **h-card** (author):
+   - p-name (author name)
+   - u-url (author URL)
+   - u-photo (avatar, optional)
+
+3. **h-feed** (index pages):
+   - p-name (feed title)
+   - p-author (feed author)
+   - Nested h-entry items
+
+### Template Updates Required
+- `/templates/base.html` - Add h-card in header
+- `/templates/index.html` - Add h-feed wrapper
+- `/templates/note.html` - Complete h-entry properties
+- `/templates/partials/note_summary.html` - Create for consistent h-entry
+
+## Effort Estimate
+- Template Analysis: 2-3 hours
+- Markup Implementation: 4-6 hours
+- CSS Compatibility Check: 1-2 hours
+- Testing with mf2 parser: 2-3 hours
+- Documentation: 1-2 hours
+- Total: 10-16 hours
