Refs #54084

Problem

Several install commands in the README, and in all of its translations, install OpenCode 1. On a machine that already has V2, running one of them replaces it with V1. The curl script is the case reported in #54084. GitHub Releases, the Scoop and Chocolatey packages, the old tap formula, opencode-bin and nixpkgs also still ship V1.

Change

I checked what each README entry installs today and pointed every V1 entry at its V2 equivalent. Where no V2 version exists, I removed the entry.

README entry	Installs today	Change
curl … opencode.ai/install	1.19.3	→ opencode.ai/v2/install (2.0.32)
npm i -g @opencode/cli@latest	2.0.32	keep
scoop install opencode	1.19.3 (Scoop Main bucket)	remove: no V2 Scoop package
choco install opencode	1.19.1 (community package)	remove: no V2 Chocolatey package
brew install anomalyco/tap/opencode	1.19.3	→ anomalyco/tap/opencode-v2 (2.0.32)
brew install opencode (homebrew-core)	2.0.32	keep
sudo pacman -S opencode (extra)	2.0.32	keep
paru -S opencode-bin	1.19.3	→ opencode-beta (2.0.32, our AUR package)
mise use -g opencode	2.0.32 (npm:@opencode/cli, min 2.0.0)	keep
nix run nixpkgs#opencode	1.19.3	→ nix run github:anomalyco/opencode (flake on dev, builds V2)
brew install --cask opencode-desktop	2.0.32	keep
scoop install extras/opencode-desktop	1.19.3	remove
Desktop link to "releases page"	GitHub Releases latest is v1.19.3	remove; keep opencode.ai/download (V2)
Desktop table opencode-desktop-windows-x64.exe	asset doesn't exist	→ opencode-desktop-win-x64.exe

These choices match the V2 docs, which use opencode-v2, opencode-beta and mise, and say that Windows package managers aren't supported.

Translations keep their existing wording. The rewritten desktop sentence drops only the releases-page link.

Out of scope

• The "Installation Directory" section is unchanged apart from the curl URL. Support for OPENCODE_INSTALL_DIR and XDG_BIN_DIR was never ported to the V2 installer; that gap is separate from this PR.
• The V1 docs site (packages/web) and the downgrade behavior of the legacy /install script.

Verification

• Checked the current version of every package against its registry: npm, Homebrew API, anomalyco/homebrew-tap, Scoop Main/Extras, Chocolatey, the AUR RPC, the Arch package search, nixpkgs master, the mise registry and GitHub Releases.
• rg 'opencode\.ai/install|scoop|choco|nixpkgs|opencode-bin|anomalyco/opencode/releases|windows-x64' README*.md → no matches

[opencode-agent]

Docs-only change that looks good. I checked the new install block in all 22 READMEs against the V2 install methods in services/www/src/docs/content/index.mdx, and they match. A search for the old install URL, opencode-ai, the desktop cask/Scoop snippet, Nix and the old install-dir variables finds nothing. The edit is the same (+4/−31) in every translation. Removing the "Installation Directory" section is correct: the repo's install script hardcodes $HOME/.opencode/bin.

Public API: unchanged.

No blocking concerns. One small, optional point: the unchanged npm i -g @opencode/cli@latest # or bun/pnpm/yarn line hides that bun needs --trust and pnpm needs --allow-build (as the V2 docs show) for the platform binary's postinstall script to run.

#52609 is an open pull request that does the same README work for README.md only, so it overlaps with this one.

Fixes #43772
