Hide console windows for child processes on Windows

[Rakly3]

On Windows, each hook run, git call and sync started by trail flashes a console window.
This adds windowsHide: true to every child-process call in src/claude/ (hooks, init, sync-run, shim-template), matching the sync spawn that already has it.

It has no effect on other platforms, and on Windows the windows no longer appear.

Ownership is git history over each area's own files, weighted towards recent work (120-day half-life). Merge commits and bots are dropped, and you are dropped from your own PR. A name with no @ has no GitHub handle in its commit email — tag them by hand, or add a .mailmap entry. A suggestion from history, not a CODEOWNERS rule.

Test signal per changed area — 1 ⚠

Reached = a node under a test path has a resolved edge into the changed symbol. It undercounts anything called indirectly — through a CLI, a spawned process or a dynamic import — so read a low ratio as “look here”, never as a coverage gate.

• ⚠ Claude Initialization — 4 of 9 reached · 3 test files reach it, none changed here
