fix(#1615): applySurface rewrites commands kind, not just skills

Codex adversarial orthogonal review of PR #1622 surfaced that applySurface (src/surface.cts) only called rewriteStagedSkillBodies for kind='skills', skipping kind='commands'. The gap meant /gsd-surface profile changes on any runtime with commands kinds (windsurf, opencode, kilo, cursor, augment, codebuddy, gemini) wrote raw @~/.claude/... references into synced command/workflow bodies, which fail at invocation time on non-Claude runtimes.

For Windsurf specifically, this left workflow files containing @~/.claude/gsd-core/commands/gsd/X.md after a profile change — paths that don't exist on a Windsurf install. Verified by the new regression test which fails before the fix (workflow bodies contained @~/.claude/) and passes after (workflow bodies reference the install target).

Captures the return value of rewriteStagedCommandBodies (temp dir path — commands rewrite uses copy-then-rewrite to avoid mutating the package source), syncs from the temp dir, then cleans up. Type annotations satisfy typescript-eslint strict mode.

Findings 2 (install ordering) and 3 (legacy .devin cleanup) from the same review are tracked in #1629 — both real but out of scope for #1615.
