Chris Farhood 7443187c4f docs: implement Phase 4 - troubleshooting guides and ADRs
Created comprehensive troubleshooting documentation:
- docs/troubleshooting/README.md - Main troubleshooting hub
- docs/troubleshooting/common-errors.md - Frequent errors and fixes
- docs/troubleshooting/controller-issues.md - Controller problems
- docs/troubleshooting/encryption-failures.md - Encryption debugging
- docs/troubleshooting/permission-errors.md - RBAC troubleshooting

Created Architecture Decision Records:
- docs/architecture/adr/README.md - ADR index
- docs/architecture/adr/001-result-types.md - Result<T,E> pattern
- docs/architecture/adr/002-branded-types.md - Compile-time type safety
- docs/architecture/adr/003-client-side-crypto.md - Browser encryption
- docs/architecture/adr/004-rbac-integration.md - Permission-aware UI
- docs/architecture/adr/005-react-hooks-extraction.md - Custom hooks

Total: 11 files, 2,847 lines added

Troubleshooting guides cover:
- Plugin installation/loading issues
- Controller deployment/connectivity problems
- Encryption/certificate errors
- RBAC permission diagnosis and fixes
- Browser-specific issues
- Network troubleshooting
- Diagnostic commands and tools

ADRs document key architectural decisions:
- Why Result types for error handling (vs exceptions)
- Why branded types for type safety (vs classes)
- Why client-side encryption (vs server-side)
- Why RBAC-aware UI (vs showing all actions)
- Why custom React hooks (vs inline logic)

Each ADR includes:
- Context and problem statement
- Decision and implementation
- Consequences (positive/negative)
- Alternatives considered with rationale
- Real-world impact and examples

# Architecture Decision Records (ADRs)
This directory contains Architecture Decision Records for the Headlamp Sealed Secrets plugin.
## What is an ADR?
An Architecture Decision Record captures an important architectural decision made along with its context and consequences.
## Format
Each ADR follows this structure:
- **Title**: Short descriptive name
- **Status**: Accepted | Superseded | Deprecated
- **Context**: What is the issue we're seeing that is motivating this decision?
- **Decision**: What is the change we're actually proposing/doing?
- **Consequences**: What becomes easier or harder as a result?
- **Alternatives Considered**: What other options did we evaluate?
## Index

## Creating New ADRs
When making significant architectural decisions:
1. Copy template:
```bash
cp docs/architecture/adr/template.md docs/architecture/adr/NNN-title.md
```
2. Fill in the template
3. Update this index
4. Link from relevant documentation
