chore: prune deleted mem0 modules from a2as.yaml and re-sign the manifest

[FlyM1ss]

PR #347 deleted Main/backend/datascraper/context_integration_enhanced.py and Main/backend/datascraper/mem0_context_manager.py, but the signed A2AS manifest (a2as.yaml) still certifies both:

• scope lists Main/backend/datascraper/context_integration_enhanced.py (a2as.yaml:10)
• imports: maps Mem0ContextManager: mem0_context_manager.Mem0ContextManager (a2as.yaml:152)
• ~12 functions: entries declare module: Main.backend.datascraper.context_integration_enhanced (a2as.yaml:257, 301, 382, 394, 400, 406, 481, 591, 597, 603, 697) plus a path: entry at a2as.yaml:770

Any A2AS-compliant tooling that resolves the manifest's module paths hits files that no longer exist (ModuleNotFoundError), or certifies stale behavior (e.g. a use_mem0 arg and EnhancedContextIntegration return type that no longer exist). The manifest correctly tracks the surviving context_integration.py / unified_context_manager.py, so the stale entries are an omission, not intentional history.

Why this wasn't fixed in PR #347: a2as.yaml carries a signatures: block (digest + ed25519 sig, a2as.yaml:16-19, issued by A2AS.org 2026-01-26). Any edit invalidates the signature, so pruning must be paired with re-signing by the issuer.

Suggested fix:

1. Remove the stale scope entry, the Mem0ContextManager import mapping, and all function/path entries referencing context_integration_enhanced.
2. Recompute the digest and obtain a fresh signature from A2AS.org.

Found by /review of PR #347 (finding 2 of 3), 2026-07-12. Nothing in-repo parses the manifest today, so there is no CI breakage — impact is limited to external A2AS verification tooling.

Heads-up for the re-sign: PR #351 deletes Main/backend/datascraper/datascraper_refactored.py (dead code, zero importers — F-9 of the 2026-07-12 hosted-docs-refresh follow-ups). a2as.yaml certifies that module in 8 places (lines 10, 193, 274, 519, 539, 545, 551, 639), so those entries join the already-listed mem0 modules in the prune list when A2AS.org re-signs.
