fix(daemon): add IPC whitelist to bypass per-client dial quota (PILOT-346)

[matthew-pilot]

Summary

Add IPCWhitelist config field so trusted local processes (known integrations) bypass the per-client dial quota (MaxConnsPerIPCClient = 4096).

Design

• On Linux, the peer PID from SO_PEERCRED is resolved to a process name via /proc/<pid>/comm
• If the process name matches an entry in IPCWhitelist, the ipcConn is marked whitelisted=true
• Whitelisted clients skip the connCount() >= MaxConnsPerIPCClient check in handleDial
• On Darwin/other, checkPeerUID returns PID=0 and whitelist is effectively disabled (graceful degradation)

Files changed

• pkg/daemon/daemon.go — +1 line (IPCWhitelist field in Config)
• pkg/daemon/ipc.go — +45/-5 (ipcConn fields, acceptLoop whitelist check, handleDial bypass)
• pkg/daemon/ipc_peercred_linux.go — +33/-6 (return PID, add resolveProcessName)
• pkg/daemon/ipc_peercred_darwin.go — +21/-5 (updated signature, no-op resolveProcessName)
• pkg/daemon/ipc_peercred_other.go — +12/-3 (updated signature, no-op resolveProcessName)
• pkg/daemon/zz_ipc_*_test.go (6 files) — mechanical signature updates

Verification

• go build ./pkg/daemon/ ✅ green (linux + darwin cross-compile)
• go vet ./pkg/daemon/ ✅ clean
• go test -run 'TestIPC|TestDial|TestConnCount|TestCheckPeerUID' ./pkg/daemon/ ✅ 31.9s, all passing

Usage

# In daemon config:
IPCWhitelist:
  - pilotctl
  - pilot-gateway
  - my-integration

Closes PILOT-346.

🤖 matthew-pilot — PR Explanation

What this PR does

Adds IPCWhitelist config field so trusted local processes can bypass the per-client dial quota (MaxConnsPerIPCClient = 4096). This prevents known integrations (e.g., pilotctl, pilot-gateway) from being throttled under heavy IPC load.

How it works

1. Linux: SO_PEERCRED → peer PID → resolve process name via /proc/<pid>/comm
2. If process name matches an entry in IPCWhitelist, the connection is marked whitelisted=true
3. Whitelisted clients skip the connCount() >= MaxConnsPerIPCClient check in handleDial
4. Darwin/other: checkPeerUID returns PID=0 — whitelist gracefully disabled (no-op)
