Refocus Scramjet vision on product outcomes

[LeanAndMean]

Summary

• Rewrite the Scramjet vision around intended capabilities, user outcomes, durable principles, and product non-goals
• Remove normative implementation details and clarify where current technical contracts are authoritative
• Align contributor docs, repository navigation, and the runtime documentation pointer with the product-vision boundary

Test plan

• Run targeted base-directives and docs-registry tests
• Run TypeScript type checking
• Run targeted Biome checks
• Search for stale authority language and removed vision-section references
• Review the rewritten vision against the acceptance criteria

Fixes #466

Automated PR Review

Critical

None.

Important

None.

Suggestions

None.

Strengths

• The rewritten vision cleanly distinguishes durable product direction from replaceable implementation mechanics while preserving Scramjet’s core principles and product boundaries.
• The documentation-authority map consistently routes current behavior and technical contracts to the package README, focused guides, source, and tests.
• The implementation remains minimum-sufficient: no new files, abstractions, dependencies, schemas, or runtime behavior were introduced.
• The focused prompt-label test directly covers the only runtime-source change, and the existing documentation-registry coverage remains applicable.
• The complete requirements and approved implementation plan from Refocus the Scramjet vision on capabilities rather than implementation #466 are satisfied; all seven review lenses found no actionable defects or omissions.

Classifications

No F/S findings were supplied. The review's empty finding set is independently supportable: the vision limits itself to outcomes and durable boundaries (packages/scramjet/docs/scramjet-vision.md:5), routes technical authority to focused documentation, source, and tests (packages/scramjet/docs/scramjet-vision.md:112, CLAUDE.md:139), and the corrected runtime label is covered by its focused test (packages/scramjet/src/base-directives.ts:46, packages/scramjet/tests/base-directives.test.ts:103). Independent validation also passed 43 targeted tests, Biome, and git diff --check.

Staged Implementation Plan

No implementation stages are required. There are no genuine issues or worthwhile nitpicks to fix.
