Orca Worker 011122d833 perf(windows): split the process table into two flag sets
MDE flags "suspicious memory activity" on the process-table reader: it
opened a handle into every process on the box and read each one's PEB on
a repeating cadence. Two changes narrow that.

Drop `Memory` outright. It cost a second
OpenProcess(PROCESS_QUERY_INFORMATION | PROCESS_VM_READ) plus
GetProcessMemoryInfo per process, and nothing reads a working set off
this table -- the Resource Manager runs its own sweep, and the addon
stores WorkingSetSize into a DWORD so anything above 4 GB wraps.

Split the rest in two. `readWindowsProcessIdentityTable[Fresh]` is a
bare Toolhelp32 walk with zero per-process handles, and returns
`WindowsProcessIdentityRow`, which has no `command` to read.
`readWindowsProcessTable[Fresh]` keeps the command line for the callers
that match on it. PTY root identity and the owner start-time probe move
to the cheap reader; agent recognition, port attribution, codex turn
processes and structured-TUI matching all genuinely need the command
line and stay.

Two independently single-flighted caches, never one per caller: the
fan-out this module prevents is one scan per caller, and each reader
still serves every caller wanting its flag set. The wedge gate and the
3s deadline stay shared, because both readers call the same addon and
one wedged read latches its one `requestInProgress`. With no binding
there is only the 1.4s PowerShell scan to run, so the identity view
rides the detailed snapshot rather than forking a second one.

Measured on Windows 11, 492 processes (p50/p95): identity 6.3/7.0 ms,
detailed 12.3/13.4 ms, previous memory+commandLine 13.1/14.1 ms.
