Subject: [PATCH 1/2] fix: implement documented install-dir override chain

OPENCODE_INSTALL_DIR > XDG_BIN_DIR > $HOME/bin > $HOME/.opencode/bin,
matching README.md's Installation Directory section. The install
script previously hardcoded $HOME/.opencode/bin and ignored both
env vars entirely.

Closes #43772

Subject: [PATCH 2/2] fix: preserve existing install location across upgrades

Checking OPENCODE_INSTALL_DIR/XDG_BIN_DIR before the new $HOME/bin
tier could silently move a user's install: someone with an existing
$HOME/.opencode/bin install and no env vars set would get a fresh
binary in $HOME/bin while their PATH still pointed at the old
location. Now an existing $HOME/.opencode/bin/opencode keeps
installing there unless an env var explicitly says otherwise.

Also re-indents the block to 2-space to match the rest of the file.

Addresses review feedback on PR #44079.
