Subject: [PATCH 1/2] fix(windows): hide console window for git child processes
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The codegraph daemon shells out to git via execFileSync without
windowsHide:true. Because the daemon is launched with detached:true
(no parent console), Windows allocates a fresh console window for
every git child. Each short-lived git invocation makes that window
flash on screen — very visible during auto-sync, where many file
writes can trigger several git calls per second.

This sets windowsHide:true on all 7 git call sites:

  - src/extraction/index.ts: shared gitOpts (covers ls-files
    --cached and -o), plus 3 inline opts for rev-parse,
    check-ignore, and status --porcelain
  - src/sync/worktree.ts:    rev-parse --show-toplevel
  - src/sync/git-hooks.ts:   rev-parse --is-inside-work-tree,
                             rev-parse --git-path hooks

mcp/index.ts already passes windowsHide:true when spawning the
detached daemon — these git call sites were missed.

windowsHide:true is a no-op on macOS and Linux.

Fixes #485

Subject: [PATCH 2/2] fix(windows): hide console window for git child processes
 in extraction

Add windowsHide:true to the 4 execFileSync call sites in
src/extraction/index.ts (1 shared gitOpts plus 3 inline option
objects for rev-parse --show-toplevel, check-ignore -q, and
status --porcelain --no-renames).

Companion to the previous commit on this branch which covered the
sync/ module. See #485 for context.
