Snapshot fails when opencode is opened in a git subdirectory (snapshot service cwd mismatch) #27688

Description

Bug Description

When opening opencode in a git repository subdirectory (e.g., src/), the snapshot service fails to track files with the error:

WARN service=snapshot exitCode=128 stderr=warning: cannot open directory 'src/src/': No such file or directory
fatal error: pathspec 'src/date.txt' did not match any files
failed to add snapshot files

Root Cause

The issue was introduced in packages/opencode/src/snapshot/index.ts.

In the stage, drop, and ignore functions, cwd is set to state.directory (the directory where opencode was launched), but files paths are relative to state.worktree (git repository root).

When --work-tree points to the repository root but cwd points to a subdirectory, git cannot resolve the paths correctly.

Affected Code

In packages/opencode/src/snapshot/index.ts:

• ignore function: cwd: state.directory should be cwd: state.worktree
• drop function: cwd: state.directory should be cwd: state.worktree
• stage function: cwd: state.directory should be cwd: state.worktree

Expected Behavior

Snapshot should work correctly regardless of which directory within a git repository opencode is launched from.
