fix(gateway): use base pythonw for post-update Windows respawn

The post-update respawn watcher (launch_detached_profile_gateway_restart)
respawned the gateway via `_gateway_run_args_for_profile`, which used
`get_python_path()` — the console `python.exe`. On uv-created venvs even
`venv\Scripts\pythonw.exe` re-execs the base interpreter as a console
`python.exe`, and that re-exec is a fresh CreateProcess that does NOT
inherit the watcher's CREATE_NO_WINDOW flag. Result: a blank console
window pops up after every Desktop-GUI `hermes update`, and the respawned
gateway is tied to it.

`hermes gateway start` already avoids this by routing through
`_resolve_detached_python` to get the base `pythonw.exe` plus a
VIRTUAL_ENV / PYTHONPATH overlay (see `_build_gateway_argv`/`_spawn_detached`).
The post-update respawn path was the one launch site that never got the
same treatment — a sibling call path of the same bug class.

Fix:
- `_gateway_run_args_for_profile` now resolves the base `pythonw.exe` on
  Windows via `_resolve_detached_python` (no-op on POSIX — argv keeps
  `get_python_path()` verbatim).
- New `_gateway_respawn_env` overlays VIRTUAL_ENV / PYTHONPATH /
  HERMES_GATEWAY_DETACHED so the base-interpreter respawn can import
  `hermes_cli` without the venv launcher shim. Returns the env unchanged
  on POSIX, preserving pre-fix spawn behaviour bit-for-bit.
- The watcher interpreter itself is resolved the same way and both
  watcher Popen calls pass the overlay env; the respawned gateway
  inherits it transitively from the watcher.

This complements #41028 / #38605, which fix the same uv-pythonw console
trap in the Scheduled-Task `.cmd` wrapper (`_build_gateway_cmd_script`,
the login path). Neither touches the post-update respawn argv this PR
fixes.

Adds tests/hermes_cli/test_gateway_update_respawn_pythonw.py:
base-pythonw resolution for uv venvs, the env overlay, a POSIX-equivalence
guard, and a live-Windows windowless-interpreter check.

-### Install with the standard installer
-
-For most contributors, the best development bootstrap is the same path users
-take: run the standard installer, then work inside the repository it cloned.
-The installer creates the Hermes venv, wires the `hermes` command, stamps the
-install method for `hermes update`, and clones the full git project into
-`$HERMES_HOME/hermes-agent` (usually `~/.hermes/hermes-agent`). That keeps your
-development environment on the same layout the CLI, updater, lazy dependency
-installer, gateway, and docs assume.
-
-```bash
-curl -fsSL https://hermes-agent.nousresearch.com/install.sh | bash
-cd "${HERMES_HOME:-$HOME/.hermes}/hermes-agent"
-
-# Add dev/test extras on top of the standard install.
-uv pip install -e ".[all,dev]"
-
-# Optional: browser tools / docs site dependencies.
-npm install
-```
-
-After that, create branches and run tests from that checkout:

-```bash
-git checkout -b fix/description
-scripts/run_tests.sh
-```
-
-### Manual clone fallback
-
-Use this only if you intentionally do not want Hermes' managed install layout
-(for example, a throwaway clone inside a container or CI job). If you install
-this way, make sure you run the `hermes` entrypoint from this venv; running the
-system `python3 -m hermes_cli.main` can pick up unrelated system Python
-packages.

-# one tool call per turn multiplies the number of round-trips — and therefore

-# searches, or safe lookups. Batching independent calls into a single
-# assistant response collapses N turns into one, cutting both latency and the
-# resent-context cost that compounds over a long conversation.
-#
-# The hermes-agent runtime already executes a batch of tool calls
-# concurrently when they are independent (read-only tools always; path-scoped
-# file ops when their targets don't overlap — see
-# run_agent._execute_tool_calls / tool_dispatch_helpers). The missing piece
-# was telling the *model* to emit those calls together in the first place.
-# Until now the only batching steer in the prompt lived in

-# got nothing. This block makes the steer universal; the now-redundant
-# Google-only bullet has been dropped so no model receives it twice.
