Cloning into /workspaces failed for the non-root node user because the base image creates the directory as root and envbuilder (Coder) does not chown it to the target user:

node ➜ /workspaces $ git clone git@github.com:bmorton/temporal-operator.git
fatal: could not create work tree dir 'temporal-operator': Permission denied

Changes

• .devcontainer/Dockerfile: Create /workspaces and chown it to node (before the trailing USER node) so the directory is writable on both the devcontainer CLI and envbuilder paths.
• scripts/verify-devcontainer.sh: Add a check asserting /workspaces is writable by the current user (via a throwaway mkdir probe) to guard against regressions.

RUN mkdir -p /workspaces && chown node:node /workspaces

Superseded by #39, which includes the /workspaces chown and the verify-script writability check from this PR.
