Taskfile: Fix runs on Windows (#5148)

## Summary

Fixes silent / partial failure of CI on Windows that started with the
migration from Make to Taskfile.

Cumulative changes in this PR:

- **`Taskfile.yml`**: switch `EMBED_SOURCES` evaluation from `python` →
`python3`. Many systems (stock macOS, modern Linux distros) only ship
`python3`, so `./task test-update` and any other task referencing
`EMBED_SOURCES` failed to evaluate locally. Matches the script's own
shebang and the rest of the file (lines 870, 884 already use `python3`).
- **`tools/task/go.mod`**: bump `github.com/go-task/task/v3` v3.49.1 →
v3.50.0. v3.50.0 includes
[go-task/task#2670](go-task/task#2670) ("fix:
Windows CI test failures and path normalization"), which applies
`filepath.ToSlash` to `ROOT_DIR`, `TASKFILE_DIR`, etc. Without it,
`{{.ROOT_DIR}}/tools/go.mod` on Windows became
`C:\a\cli\cli/tools/go.mod` — backslashes were eaten as escape sequences
by the embedded `mvdan/sh` interpreter, mangling the path so `go tool
-modfile=...` could not find the file.
- **CI workflows + acceptance test helper**: invoke Task via `go tool
-modfile=tools/task/go.mod task <target>` instead of `./task <target>`.
The wrapper depends on a shell (sh/bash/pwsh) and Go's `os/exec` doesn't
use one — this surfaced as `exec: "..\\task": executable file not found
in %PATH%` from `BuildYamlfmt` on Windows. The `./task` wrapper is kept
for human/agent use (Makefile, docs, comments, error-message
instructions) — it's still the convenient and allowlistable entry point.
Affected files: `.github/actions/setup-build-environment/action.yml`,
`.github/workflows/check.yml`, `.github/workflows/push.yml`,
`.github/workflows/python_push.yml`, `acceptance/acceptance_test.go`.
- **`shell: bash` on cross-OS jobs in `push.yml`**: pin the four matrix
jobs that include Windows (`test`, `test-exp-aitools`, `test-exp-ssh`,
`test-pipelines`) to `defaults.run.shell: bash`. PowerShell mangles
`-modfile=tools/task/go.mod` (drops `.mod`); `shell: bash` resolves to
Git Bash on Windows runners and to bash on Linux/macOS.

## Test plan

- [ ] Windows test jobs run real tests (not 6-second no-ops) and produce
gotestsum output
- [ ] Linux/macOS test jobs unchanged
- [ ] `./task test-update` works locally on systems with only `python3`
