Add revision histories for first 10 tutorials

[mwunderl]

Summary

Adds REVISION-HISTORY.md to each of the first 10 tutorial directories, documenting the iteration history of each asset variant.

Format

Each file has one section per variant (Shell, CloudFormation, SDK for Python, etc.) with subsections per iteration:

## Shell (CLI script)

### 2025-07-29 v-b1 initial attempt
- Type: functional
- Initial CLI script generated from source topic

### 2026-04-13 v1 published
- Type: functional
- Security and consistency updates

Versions use v-b1, v-b2 for pre-release iterations and v1, v2 for published versions.

Revision history

• Generated from git commit history for each tutorial directory
• Only includes Shell variant (merged to main). CloudFormation and SDK entries will be added when those PRs merge.
• Future asset iterations will be logged by the generating agent as part of the content rules (AGENTS.md rule 7)
