fix(recipe-runner): auto-update rust runner binary on version mismatch (#4189)

[rysweet]

Summary

Fixes ensure_rust_recipe_runner() to upgrade the binary when it's present but outdated, not just when it's absent.

Root Cause

ensure_rust_recipe_runner() previously returned True immediately if any binary was found via is_rust_runner_available(), even if check_runner_version() would have returned False.

Changes

• src/amplihack/recipes/rust_runner.py: Split the early-return check into two cases:
  1. Present + compatible → return True immediately (unchanged behaviour)
  2. Present + outdated → log a message and fall through to cargo install to upgrade
• Updated docstring to reflect new behaviour
• docs/atlas/ast-lsp-bindings/: Refreshed atlas layer 8 to clear CI staleness check

Closes #4159
Related: #4188, #4169

PR Triage Report

Risk: 🟢 Low | Priority: Medium | Type: Bug fix

Assessment

Targeted fix for ensure_rust_recipe_runner() to upgrade outdated binaries (closes #4159). Change is scoped to src/amplihack/recipes/rust_runner.py plus atlas doc refresh.

⚠️ Possible supersession: PR #4203 modifies the same file (src/amplihack/recipes/rust_runner.py) as part of a broader smart-orchestrator teardown fix. Verify whether #4203 already includes this fix before merging to avoid conflicts or duplicate changes.

⚠️ Base drift: Base SHA 6966ad20 does not match current main (9a218fe7). Rebase required before merge.

Recommendation

Hold pending #4203 review. If #4203 subsumes this fix, close this PR. Otherwise, rebase and merge independently.
