[Bug]: Project `.claude/commands/*.md` never appear in the `/` menu for Claude; the per-workspace refresh only scans `.claude/skills`

Area

apps/server

Steps to reproduce

1. Use the Claude provider on the desktop app with a local project that has a command file at <project>/.claude/commands/start-session.md.
2. Open a thread in that project.
3. Type /start.

Expected behavior

The / menu lists /start-session, the same as the Claude Code TUI when launched in <project>.

Actual behavior

The menu shows user and plugin commands plus the project's .claude/skills/* entries, but no project .claude/commands/* entries. Claude Code does load them: the agent in the same thread lists start-session among its available commands.

Mechanism, from reading server.asar (apps/server/dist/bin.mjs) in 0.0.42:

• probeClaudeCapabilities runs with cwd from ServerConfig, which is the server's own working directory. slashCommands comes from that probe's init.commands, so it never includes a project's commands.
• snapshotForCwd for the Claude driver returns { ...machineSnapshot, skills }. discoverClaudeSkills(config, cwd) reads only <configDir>/skills and <cwd>/.claude/skills. slashCommands stays the machine-wide list, and <cwd>/.claude/commands is never read.
• persistProvider strips workspaceSnapshots, so ~/.t3/caches/claudeAgent.json holds only the machine list (253 commands here, none of them project commands).

Suggested fix: have the Claude snapshotForCwd also scan <cwd>/.claude/commands/**/*.md (subfolders become dir:name) and merge the results into slashCommands. Or run the capability probe with the workspace cwd.

Impact

Commands defined in a project can't be found from the menu. Users with a team or workspace command set have to know each name and type it in full.

Version or commit

T3 Code desktop 0.0.42, Claude Code 2.1.273

Environment

Windows 11, local connection

Workaround

Type the full command name without autocomplete. The command should still reach Claude Code, but I have not confirmed this on this build.

Start in apps/server by locating the Claude driver’s snapshotForCwd, discoverClaudeSkills, and probeClaudeCapabilities entry points described in the issue. Reproduce with a project containing .claude/commands/start-session.md, then trace how slashCommands reaches the menu. Done means project command files appear as /start-session entries without removing existing user or plugin commands.
