What does this PR do?

PR #24849 introduced hierarchical path filtering (eq(path, X) OR like(path, X + "/%")) for git repos to support worktrees. But non-git projects set worktree = "/" (a truthy value), so the TUI's sessionListQuery() check !worktree never triggered — it fell through to the path branch instead.

path.relative("/", "/root/oc") → "root/oc" then matched ALL sessions under /root/oc/ hierarchically, including sessions from unrelated subdirectories.

Changes:

1. packages/tui/src/context/sync.tsx: Check worktree === "/" explicitly and return { directory } for non-git projects so the server's existing eq(directory) fallback is used.
2. packages/opencode/src/cli/cmd/session.ts: Pass directory: process.cwd() to CLI session list so it's also scoped.

The server already has the else if (scope !== "project") fallback that performs eq(directory, ...) matching - no server changes needed. Git repo hierarchical filtering is untouched.

How did you verify your code works?

Tested locally with a local build:

• TUI session list from a non-git directory shows only sessions from that directory
• CLI session list from a non-git directory shows only sessions from that directory
• Git repo sessions continue to use hierarchical path filtering as intended by feat(core): filter sessions by path and add setting to disable #24849

Potential Duplicates Found

PR #29026 - fix(tui): scope session list to current worktree directory

• fix(tui): scope session list to current worktree directory #29026
• Why related: Directly addresses the same issue of scoping session lists to the current directory/worktree, which is the core fix in PR fix(tui): scope non-git sessions by directory, not hierarchical path #31210.

PR #29582 - fix(tui): show home sessions in global project

• fix(tui): show home sessions in global project #29582
• Why related: Related to session scoping and filtering logic in the TUI.

PR #20361 - fix(sdk): avoid implicit directory filtering on /session list

• fix(sdk): avoid implicit directory filtering on /session list #20361
• Why related: Addresses similar directory filtering issues on session list endpoints.

• fix(tui): handle non-git project paths in autocomplete and session fi… #29539
• Why related: Specifically handles non-git project path handling in session-related features.

This PR focuses on non-git directory filtering, restoring the behavior to what it was pre-#24849 (while not impacting that PR's intent for git repos). The 4 potential duplicates address different problems:

• fix(tui): scope session list to current worktree directory #29026 (scope session list to current worktree directory) - Git worktrees. Sends directory + path for git repos and adds a UI toggle. Still has the same !worktree bug for non-git (worktree = "/" is truthy) - doesn't fix that case.

• fix(tui): show home sessions in global project #29582 (show home sessions in global project) - Different edge case. When launched from home, the global project reports worktree = "/" and filters hide older home sessions stored with empty path. Not related to non-git directory filtering.

• fix(sdk): avoid implicit directory filtering on /session list #20361 (avoid implicit directory filtering on /session list) - Opposite direction. Wants to relax filtering so worktree users see project sessions from nested directories. This PR tightens filtering for non-git.

• fix(tui): handle non-git project paths in autocomplete and session fi… #29539 (handle non-git project paths in autocomplete and session filter) - Catches the same worktree === "/" but only returns { scope: "project" } (no filtering). This PR returns { directory } which actually enables exact directory filtering for non-git. It also fixes CLI session list. fix(tui): handle non-git project paths in autocomplete and session fi… #29539 and this are complementary - fix(tui): handle non-git project paths in autocomplete and session fi… #29539 fixes autocomplete, this fixes session list filtering and CLI.

All 4 remain open. None supersede this fix.
