Fix desktop authorized evolution proposal execution

[cursor]

Summary

• Fixes a critical desktop evolution bug where authorizing a capability proposal could leave that proposal queued while a background forced run executed an unrelated proposal.
• Root cause: the desktop authorization path passed the captured proposal_id only through SKILLLITE_EVO_FORCE_PROPOSAL_ID, but skilllite evolution run clears that env var when --proposal-id is not present.
• Fix: pass --proposal-id <proposal_id> in the desktop background run args and update the regression test to assert both workspace and proposal id are included.

Task Linkage

• Task ID: TASK-2026-070
• Task folder: tasks/TASK-2026-070-critical-bug-sweep-2026-07-06/

Injected Specs

• spec/architecture-boundaries.md (reviewed; no dependency/layering change)
• spec/security-nonnegotiables.md (not directly applicable; no sandbox/security policy change)
• spec/testing-policy.md (required for code change)
• spec/docs-sync.md (reviewed; no docs needed because existing CLI flag semantics are reused)
• Additional injected specs: spec/verification-integrity.md, spec/task-artifact-language.md, spec/structured-signal-first.md, spec/capability-gap-evolution.md, spec/rust-conventions.md

Validation Evidence

• Commands executed:
  • git log --oneline --decorate -n 20
  • rustfmt --check --edition 2021 crates/skilllite-assistant/src-tauri/src/skilllite_bridge/integrations/evolution_ui/authorize.rs
  • python3 scripts/validate_tasks.py
  • cargo test --manifest-path crates/skilllite-assistant/src-tauri/Cargo.toml authorized_run_args_include_target_workspace_and_proposal
  • cargo clippy --all-targets -- -D warnings
  • cargo test
• Key results:
  • Changed-file rustfmt: passed.
  • Task validation: Task validation passed (70 task directories checked).
  • Targeted Tauri test: authorized_run_args_include_target_workspace_and_proposal ... ok (1 passed).
  • Workspace clippy: passed.
  • Workspace tests: passed.
  • Note: full cargo fmt --check --manifest-path crates/skilllite-assistant/src-tauri/Cargo.toml reports unrelated pre-existing formatting diffs across excluded Tauri files; changed file was checked directly.

Regression Scope

• Areas likely affected:
  • Desktop user-authorized capability evolution background execution.
• Explicit non-goals:
  • Refactoring cmd_run env cleanup semantics.
  • Broad Tauri formatting cleanup.
  • Changing CLI flags, docs, or user command syntax.

Docs Sync (EN/ZH)

• Not needed
• Updated EN + ZH docs
• Files:
  • N/A; no user-visible CLI/env/docs semantics changed.
