.SYNOPSIS
Ensure Git (and Git Bash) are installed. Git for Windows bundles bash.exe
which Hermes uses to run shell commands.
Priority order (deliberately simple -- no winget, no registry, no system
package manager):
1. Existing ``git`` on PATH -- use it as-is (the common fast path).
2. Download **PortableGit** from the official git-for-windows GitHub
release (self-extracting 7z.exe) and unpack it to
``%LOCALAPPDATA%\hermes\git`` -- never touches system Git, never
requires admin, works even on locked-down machines and machines
with a broken system Git install.
**Why PortableGit, not MinGit:** MinGit is the minimal-automation
distribution and ships ONLY ``git.exe`` -- no bash, no POSIX utilities.
Hermes needs ``bash.exe`` to run shell commands. PortableGit is the
full Git for Windows distribution without the installer UI; it ships
``git.exe`` + ``bash.exe`` + ``sh``, ``awk``, ``sed``, ``grep``, ``curl``,
``ssh``, etc. in ``usr\bin\``.
We deliberately skip winget because it fails badly when the system Git
install is in a half-installed state (partially registered, or uninstall-
blocked). Owning the Hermes copy of Git ourselves is predictable and
recoverable: if it ever breaks, ``Remove-Item %LOCALAPPDATA%\hermes\git``
and re-running this installer fully recovers.
After install we locate ``bash.exe`` and persist the path in
``HERMES_GIT_BASH_PATH`` (User scope) so Hermes can find it in a fresh
shell without a second PATH refresh.

# ============================================================================
# Stage protocol
# ============================================================================
#
# install.ps1 supports a small, stable "stage protocol" that lets programmatic
# callers (the desktop GUI's onboarding wizard, CI, future install.sh, etc.)
# drive the install one step at a time and surface progress/errors with their
# own UI. CLI users running the canonical `irm | iex` one-liner never
# encounter this -- default invocation behaves exactly as before.
#
# Entry points:
#
# install.ps1 Interactive install (today's behavior).
# install.ps1 -ProtocolVersion Emit the protocol version integer.
# install.ps1 -Manifest Emit the stage manifest as JSON.
# install.ps1 -Stage <name> Run one stage and emit its result.
# install.ps1 -NonInteractive Disable all Read-Host prompts (also
# skips the setup wizard and the gateway
# autostart prompt). Can be combined
# with default invocation to do a full
# non-interactive install.
# install.ps1 -Json Emit machine-readable JSON instead of
# the human-readable success banner at
# the end of a full install.
#
# Manifest schema (the JSON returned by -Manifest):
#
# {
# "protocol_version": 1,
# "stages": [
# {
# "name": "uv",
# "title": "Installing uv package manager",
# "category": "prereqs",
# "needs_user_input": false
# },
# ...
# ]
# }
#
# Stage result (the JSON written by -Stage <name>):
#
# {
# "stage": "uv",
# "ok": true,
# "skipped": false,
# "reason": null,
# "duration_ms": 1234
# }
#
# Exit codes:
#
# 0 -- success (stage ran, or stage was deliberately skipped).
# 1 -- generic failure; the stage threw.
# 2 -- unknown stage name passed to -Stage.
#
# Adding a stage:
#
# 1. Append an entry to $InstallStages below.
# 2. Make sure the worker function it points at is idempotent and respects
# $NonInteractive when it has prompts. Add it before "configure"
# (the wizard) or "gateway" (autostart) if it should run unconditionally;
# after those if it's optional post-install glue.
# 3. Do NOT bump $InstallStageProtocolVersion -- adding stages is additive.
# Drivers iterate the manifest dynamically.
#
# ============================================================================
# Stage definitions -- the single source of truth. Each entry maps a stable
# stage name (the API contract drivers depend on) to the worker function that
# implements it. ``Title`` is what UIs show; ``Category`` lets UIs group
# stages; ``NeedsUserInput`` tells UIs "this stage prompts -- either skip it
# or arrange to provide answers another way."
