docs: Add documentation metadata and revision history (#65)

[LGSI-KarumuriHari]

📝 PR Description

This PR implements standardized documentation metadata headers and revision history tracking across all Eclipse timpani documentation files to ensure proper traceability, version control, and attribution.

Changes Implemented:

1. Documentation Metadata Headers Added (27 files)

Added to all documentation files:

• Document Information section with:

  • Issuing Author (Eclipse timpani Team)
  • Unique Configuration ID following naming convention
  • Document Status (Published)
  • Last Updated date (2026-05-13)

• Revision History table with columns:

  • Version (0.0a - alpha release)
  • Date (2026-05-13)
  • Comment (Initial creation)
  • Author (Eclipse timpani Team)
  • Approver (-)

2. Configuration ID Assignment

LLD Documents (22 files):

• timpani-o: timpani-o-lld-01 through timpani-o-lld-10
• timpani-o: timpani-o-lld-index (README)
• timpani-n: timpani-n-lld-01 through timpani-n-lld-10
• timpani-n: timpani-n-lld-index (README)

Architecture Documents (2 files):

• timpani-arch-system (timpani_architecture.md)
• timpani-arch-grpc (timpani_rust_grpc_architecture.md)

Project Documentation (3 files):

• timpani-api-reference (api.md)
• timpani-doc-structure (structure.md)
• timpani-doc-index (README.md)

3. Version Numbering Convention

Alpha Versioning (0.0a):

• All documents start at version 0.0a to indicate initial alpha/draft status
• Follows semantic versioning with alpha designation for pre-release documentation
• Provides clear indication that documents are in initial state

4. Contribution Guidelines Update

Added Section 7: Documentation Metadata Standards

• Complete metadata header template with examples
• Configuration ID naming conventions and format rules
• Document status values (Draft, Review, Approved, Published)
• Revision history guidelines with versioning rules
• Alpha versioning convention (0.0a for initial documents)
• Example revision history entries
• Files requiring metadata (complete list)
• Metadata maintenance procedures
• Verification checklist for documentation changes

Files Modified Summary:

Total: 28 files

• LLD Documents: 22 files (timpani-o: 11, timpani-n: 11)
• Architecture: 2 files
• Project Docs: 3 files
• Guidelines: 1 file (contribution/guidelines-en.md)
