README: manual-download table omits Windows binaries

[chirag127]

The 'Download Binary Manually' section of the README lists macOS and Linux binaries but not Windows, even though the v0.9.0 release ships both gocode_0.9.0_windows_amd64.zip and gocode_0.9.0_windows_arm64.zip.

Current table (README.md, Installation → Download Binary Manually):

Platform	File
macOS (Apple Silicon)	gocode_*_darwin_arm64.tar.gz
macOS (Intel)	gocode_*_darwin_amd64.tar.gz
Linux (x86_64)	gocode_*_linux_amd64.tar.gz
Linux (ARM64)	gocode_*_linux_arm64.tar.gz

Suggested additions:

| Windows (x86_64) | gocode_*_windows_amd64.zip |
| Windows (ARM64) | gocode_*_windows_arm64.zip |

Also worth noting for Windows users doing manual install (not via install.ps1): the extracted binary is gocode.exe, and the PowerShell installer drops it into $env:LOCALAPPDATA\Microsoft\WindowsApps for PATH inclusion. A one-liner under the table ("Windows: extract the zip and place gocode.exe somewhere on PATH, e.g. $env:LOCALAPPDATA\Microsoft\WindowsApps") would save people a step.

Impact: low-effort README fix; unblocks Windows users who prefer manual install over piping remote scripts to iex.

Closing — we've dropped this agent from our fleet (moving to a smaller set of 4). Not something wrong with the tool; just consolidating. Feel free to keep or dismiss for your own tracking.

Reopening — reversing the earlier close. These reports still describe real gaps in the tool and are useful signal regardless of our own usage decisions. Ignore the earlier close comment; feel free to triage on merit.
