chore: remove the root go.work workspace file

[taliesin-ai]

What

Removes the root go.work workspace, and the CI plumbing that only existed to support it.

After the webview2 fold (#5711) the workspace covered a single module, ./v3, and every CI workflow already sets GOWORK: "off", so it only ever affected local development. There it did more harm than good:

• An active workspace shadows the standalone example modules nested under v3/. That is why v3/examples/mac-window-tabs has to force GOWORK: "off" in two Taskfiles: without it, binding generation finds 0 services and go mod tidy targets v3 instead.
• It forced build-and-test-v3.yml to run go work use . on each generated template project so Go 1.25 workspace mode would not reject it.

Contributors who want a workspace can still create one; it is now gitignored so it stays local.

Changes

• delete go.work and go.work.sum
• build-and-test-v3.yml: drop the go.work / go.work.sum path filters, both cache keys, and the go work use . step
• cross-compile-test-v3.yml: drop the same filters and cache key
• .gitignore: ignore go.work and go.work.sum
• mac-window-tabs Taskfiles: keep GOWORK: "off" (still correct defensively, for contributors with a local workspace) but reword the comments, which referred to a root workspace that no longer exists

Second commit, while in the same lines: the webview2/** path filters and webview2/go.sum cache entries in both workflows have been dead since the module was folded into v3/internal/webview2. Removed.

Verification

• go build ./... in v3/ with no workspace active: clean
• a module created at the repo root builds with nothing to reject it, which is what the removed go work use . step was compensating for
• both workflows and both Taskfiles parse as YAML
• no go work invocation remains anywhere in the repo

Walkthrough

V3 CI workflows now use V3-specific path filters and Go cache inputs. Template builds no longer register generated projects with Go workspaces. Local go.work files are ignored, and example task comments explain forced workspace disabling.

Changes

V3 workspace and CI behavior

Layer / File(s)	Summary
Narrow V3 workflow scope and caching .github/workflows/build-and-test-v3.yml, .github/workflows/cross-compile-test-v3.yml	Workflow triggers and Go cache dependencies now focus on V3 files and the workflow definitions.
Simplify generated template builds .github/workflows/build-and-test-v3.yml	Template testing no longer runs go work use . before wails3 build.
Handle local Go workspaces .gitignore, v3/examples/mac-window-tabs/Taskfile.yml, v3/examples/mac-window-tabs/build/Taskfile.yml	Local Go workspace files are ignored, and task comments document forced workspace disabling.

Poem

I’m a rabbit with a tidy burrow,
Go work files tucked away from view.
V3 builds hop on their own path,
Templates bloom without workspace glue.
CI follows the freshest trail—
And every task knows what to do.

Verified locally: v3 builds with no workspace active, and a module created at the repo root builds without workspace rejection (what the removed go work use . step was compensating for). CI template builds are the real test and are green so far.

The webview2 filter cleanup in the second commit is dead-reference removal from the same lines, no behaviour change.
