fix: remove hardcoded CORA project references (#121)

The plugin had hardcoded references to 'CORA' (Every's internal project)
throughout the documentation workflow, making it project-specific rather
than generic. This affected users trying to use the plugin on non-CORA
projects.

Changes:
- Replace 'cora-critical-patterns.md' with 'critical-patterns.md'
- Replace 'Which CORA module' with 'Which module or component'
- Replace 'CORA-Specific Resources' with 'Project-Specific Resources'
- Replace 'CORA-MODULES.md' with 'modules documentation'
- Replace 'CORA system' with 'System-wide' in templates
- Update cora-test-reviewer description to be generic

Files modified:
- learnings-researcher.md: Fixed critical patterns file reference
- compound-docs/SKILL.md: Removed module and filename hardcoding
- compound-docs/assets/*.md: Generalized template references
- workflows/compound.md: Changed 'CORA schema' to 'solution schema'
- workflows/work.md: Made test reviewer description generic

This makes the plugin truly project-agnostic as advertised.
