Fix Windows connectivity & lifecycle bridges for Antigravity, OpenCode, and Codex

Problem / Motivation

On Windows installations, connecting Antigravity (agy) and OpenCode (opencode) fails to establish a working two-way bridge with Munder Difflin due to schema mismatches and missing configuration declarations:

1. Antigravity (agy) Stop hook never fires:

   • In src/main/hive.ts (installAgyHooks), PreInvocation, PostInvocation, and Stop hooks are written with a nested { hooks: [{ type: 'command', command: ..., timeout: 0 }] } wrapper.
   • Per the Antigravity CLI lifecycle specification, PreInvocation, PostInvocation, and Stop must be a flat array of handler objects: [{ type: "command", command: "...", timeout: 30 }]. Only PreToolUse and PostToolUse use the { matcher, hooks } grouping.
   • Because Stop is nested, Antigravity's hook loader fails to parse and execute Stop. As a result, Munder Difflin never receives the idle notification and never drains the agent's inbox, causing the agent to appear stuck.
   • In addition, timeout: 0 causes immediate timeouts if invoked.
   • On Windows, agy is frequently installed as %LOCALAPPDATA%\agy\bin\agy.exe or %USERPROFILE%\.local\bin\antigravity.cmd, which are not currently searched by winCandidates in pty.ts and shellEnv.ts.

2. OpenCode (opencode) bridge plugin is never loaded:

   • In src/main/hive.ts (installOpenCodePlugin), hive-bridge.js is written to <agentDir>/.opencode/plugins/, but opencode.json is generated with only { "theme": "system" }.
   • OpenCode does not auto-scan plugin folders without an explicit declaration in opencode.json under "plugin": ["./plugins/hive-bridge.js"] (verified via opencode debug config). Without this entry, the plugin is completely ignored.
   • In src/main/index.ts (spawnAgentCore), dynamic serialization of OPENCODE_CONFIG_CONTENT does not inject the plugin array, overriding any local opencode.json.
   • In OPENCODE_PLUGIN, session tracking is missing: extracting sessionID on session.idle and session.created is needed for session registration and cost tracking.
   • OpenCode's auto mode in agentProvider.ts lacked --auto and --dangerously-skip-permissions flags, leaving auto mode ineffective.

3. Auto Mode posture for non-Claude providers:

   • In src/main/index.ts (around line 2746), argsWithAutoModeFlag is only executed under if (opts.hive && claudeProvider). Non-Claude providers spawned by the main process (or restored agents) do not receive their auto-mode flags.

Proposed Solution

1. src/main/hive.ts:

   • Update installAgyHooks:

     const tool = (event: string) => ({
       matcher: '*',
       hooks: [{ type: 'command', command: this.nodeRunUnquoted(shim, event), timeout: 30 }]
     });
     const plain = (event: string) => ({
       type: 'command',
       command: this.nodeRunUnquoted(shim, event),
       timeout: 30
     });

   • Also target ~/.gemini/antigravity/hooks.json in addition to config and antigravity-cli.
   • Update installOpenCodePlugin to explicitly register plugin: [fileUrl, './plugins/hive-bridge.js'] in opencode.json.
   • Update OPENCODE_PLUGIN to extract session_id from input.sessionID || input.event.sessionID and handle session.created / session.start.

2. src/main/index.ts:

   • In spawnAgentCore, inject oc.plugin into OPENCODE_CONFIG_CONTENT when OPENCODE_CONFIG_DIR is present.
   • Run argsWithAutoModeFlag in the non-Claude hive spawn branch so all providers receive their auto-mode bypass posture.
   • Expand tools:status resolution to check aliases (agy / antigravity).

3. src/main/pty.ts & src/main/shellEnv.ts:

   • Add candidate Windows paths for agy.exe, antigravity.cmd, and codex.cmd in winCandidates.

4. src/shared/agentProvider.ts:

   • Set OpenCode autoModeFlag: '--dangerously-skip-permissions --auto', autoFlag: '--dangerously-skip-permissions --auto', and resumeFlag: '-s'.
   • Add duplicate protection in buildSpawnCommand.
