fix(evolution): scope destructive reset to requested workspace

[cursor]

Summary

• Fix evolution reset --force potentially deleting global/default chat evolution data while leaving the requested project's evolved skills active.
• Add --workspace/-w (default .), route every reset mutation through that workspace, and remove _evolved from both skills/ and .skills/ because runtime discovery scans both.
• Add a cross-workspace isolation regression test and synchronized EN/ZH command docs.

Task Linkage

• Task ID: TASK-2026-071
• Task folder: tasks/TASK-2026-071-evolution-reset-workspace-scope/

Injected Specs

• spec/architecture-boundaries.md
• spec/security-nonnegotiables.md (not a sandbox/security-policy change)
• spec/testing-policy.md
• spec/docs-sync.md

Validation Evidence

• Commands executed:
  • cargo test -p skilllite --test cli_evolution_workspace evolution_reset_workspace_flag_isolates_all_destructive_changes -- --exact
  • cargo test -p skilllite
  • cargo test
  • cargo fmt --check
  • cargo clippy --all-targets -- -D warnings
  • cargo clippy --all-targets -- -D warnings -A clippy::question_mark -A clippy::useless_borrows_in_formatting
  • python3 scripts/validate_tasks.py
• Key results:
  • Regression, package, and full workspace tests passed.
  • Formatting and task validation passed.
  • Strict Clippy is baseline-blocked by two untouched Rust 1.97 lints in scan.rs and skill/add/admission.rs; the full workspace passes when only those exact pre-existing categories are exempted.

Regression Scope

• Areas likely affected:
  • Evolution reset CLI parsing, dispatch, and destructive path resolution.
• Explicit non-goals:
  • Workspace cleanup for disable, explain, or repair-skills.
