Fix azd ext install --force to reinstall when version matches

[Copilot]

The --force flag was ignored when the installed version matched the target version, preventing recovery when extension files were missing but metadata indicated installation.

Reproduction:

azd ext install microsoft.azd.extensions  # Install extension
rm -rf ~/.azd/extensions/                  # Delete files, metadata remains
azd ext install microsoft.azd.extensions --force  # Skips: "version already installed"

Changes

• Core logic (extension.go:628): Check --force flag before skipping same-version installs

  // Before: always skipped
  if installedExtension.Version == targetVersion {
  
  // After: skip only when force not set
  if installedExtension.Version == targetVersion && !a.flags.force {

• Flag description (extension.go:536): Updated help text to reflect reinstall capability

  "Force installation, including downgrades and reinstalling the same version"
  

With --force, the extension now uses the upgrade path (uninstall + reinstall) to restore missing files.

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

This section details on the original issue you should resolve

<issue_title>azd ext install --force should force install</issue_title>
<issue_description>Right now, it seems that running azd ext install --force only forces the version check downgrade, but does not install if the version is "up-to-date".

It may be extremely useful to have a --force option mean "always grab and patch regardless of what the local metadata says". This would help for recovery in cases where something bad has gone wrong on the user's machine, and the user needs a failsafe option to recover.

Repro:

1. Delete ~/.azd/extensions/ directory
2. Run azd ext install --force microsoft.azd.extensions

Expected: Installation should occur
Actual: Received the following skipped message.
