Standardize optional Session runtime projection

[luokerenx4]

What changed

• Make a missing legacy Session runtime binding upgrade to explicit native-runtime ownership instead of adopting the Workspace's current provider.
• Keep credential, model, and effort independent optional launch values and project them through every Agent adapter activation path.
• Fix Quick Chat's login-backed provider switch so the selected credential contributes its own model/effort rather than the previous Workspace model.
• Carry the same atomic selection through Workspace Manager and update launch ownership copy to state that Workspace files remain unchanged.
• Add cross-adapter, route, UI, and legacy-resume regression coverage; update the owner guide and completed execution plan.

Root cause

Login-backed runtimes used a UI resolver branch that always preferred detected Workspace metadata, even after the user explicitly selected another credential. Separately, legacy resume identities without a persisted binding were reconstructed from mutable Workspace files during resume/WebPi/headless activation, so their effective provider could change after Session creation.

Impact

New and resumed Sessions now have stable, truthful process-level runtime inputs. A native binding may omit OpenAlice credentials entirely while still carrying model/effort overrides, and remembered explicit provider choices stay visible and are submitted atomically.

Verification

• npx tsc --noEmit
• pnpm -C ui exec tsc -b
• 151 focused Session/runtime/UI route tests
• Workspace Issue/scheduling focused suite
• Managed-runtime and desktop-package focused suites
• Full pnpm test: 3946 tests executed; nine unrelated parallel-load timeouts, all nine passed on immediate focused rerun (49/49)
• Real pnpm dev browser walk: GLM Workspace -> DeepSeek shows deepseek-v4-flash, Session-only ownership copy, and matching Manager model/effort
• CSC_IDENTITY_AUTO_DISCOVERY=false pnpm electron:smoke:workspace (packaged managed-Pi scheduled Issue acceptance passed and cleaned up)
