fix(web): normalize portable launch entry identity

[ScriptedAlchemy]

Summary

• Normalize path-shaped stdio arguments inside the artifact against their effective working directory before computing /web launch identity.
• Treat the real portable cwd + relative entry emission as equivalent to host projections that name the same artifact entry absolutely.
• Preserve AB8023 when projections resolve to genuinely different artifact entries.

Follow-up to #628.

Tests

• TDD red: the real portable-plus-Claude fixture failed with AB8023 launch ambiguity before the fix.
• pnpm build
• pnpm typecheck
• pnpm lint
• pnpm test:unit — 4,123 passed, 6 skipped
• focused web-host/web-launch/MCP-session suite — 68 passed

Deslop

GPT-5.6 Sol, 1 edit — replaced exception-driven containment with isInsideOrEqual; no behavior change.

Self-review

Reviewer: gpt-5.6-sol-medium (change-risk-reviewer) over exact e9db67a32 vs origin/main (efdec6bc).

No concrete merge risks found. Reviewed effective-cwd path normalization and containment, false equivalence versus false AB8023, actual portable adapter emission, materially different entries, three-file scope, patch changeset, and documentation requirements. No fixes or dismissals were required.
