What does this PR do?

Fixes issue #15678 where opencode session list returns empty results when run inside a Git repository.

The bug was caused by using Session.list() which filters by current project ID. When running inside a Git repo, it only shows sessions for that specific project. Changed to Session.listGlobal() which shows all sessions regardless of current project/git context.

How did you verify your code works?

Analyzed the code and confirmed the fix works.

Local tests pass:
test/server/session-list.test.ts: 5 pass

Based on my search, I found one potentially related PR:

Related PR:

• PR feat(cli): add -a global mode for session list #15178 - feat(cli): add -a global mode for session list
  • This PR addresses a similar concern about listing sessions globally vs. in current context. It adds a -a flag for global mode, which is related to the issue this PR fixes (making global listing the default behavior).

However, PR #15178 and PR #15772 (current PR) appear to address the same underlying issue from different angles - one adds a flag option while the current PR changes the default behavior to always list globally.

No other duplicate PRs found that directly address the same fix.

@adiled if this is a feature, is there a way to revert this change by showing all sessions regardless of context in a config file or something? This is painful for those who work multi-repos and start opencode in a common workspace folder

UPDATE: I think my issue is different, Created a PR and a related issue for it #16273
