xarmian 665f1918a7 feat(cli): headless admin bootstrap via --email/--name/--password (BUG-988) (#761)
* feat(cli): headless admin bootstrap via --email/--name/--password (BUG-988)

Adds non-interactive flags to `pad auth setup` and `pad init` so agents
running inside Claude Code or other non-TTY environments can bootstrap a
fresh Pad instance without hitting interactive prompts that block forever.

- New flags --email, --name, --password on both commands; all three must
  be supplied together when any one is present (clear error naming the
  missing flag otherwise). Checked before the remote-mode guard so the
  headless path works on any server host — the loopback gate is enforced
  server-side.
- runHeadlessSetup() drives the existing POST /api/v1/auth/bootstrap
  endpoint directly, saves credentials, and respects --format json (emits
  a LoginResponse-shaped object with user + token). Already-initialized
  conflict produces a structured JSON error object under --format json.
- `pad init` slots headless bootstrap into the bootstrap step only; the
  rest of init (config, workspace creation, skill install) continues.
- Hardens readPassword() with an early non-TTY guard (generic message).
- Hardens promptAndBootstrap() with a bootstrap-specific non-TTY guard
  (points at --email/--name/--password flags) so --cli-prompt on a pipe
  exits immediately rather than blocking.
- Extends `pad init` non-TTY error message to mention the new flags.
- Five new tests in cmd/pad/setup_headless_test.go covering success,
  missing-flag validation, non-TTY guard, already-initialized conflict,
  and the full init flow including workspace creation.

NOTE: --password is visible in process listings (inherent to flag-based
injection). Env-var bootstrap (PAD_ADMIN_*) is the tracked follow-up.

* fix(cli): thread bootstrap token, factor shared core, restore readPassword fallback

Round-1 codex findings:

1. Bootstrap token not sent on headless path (BLOCKER)
   Add BootstrapWithToken(email, name, password, token) to cli.Client that
   sets X-Bootstrap-Token when token is non-empty. Export ReadBootstrapToken
   from internal/cli/bootstrap.go (was readBootstrapToken) so cmd/pad can
   call it. Extract doHeadlessBootstrap(cfg, client, email, name, password)
   as the shared core for both setupCmd and padInitCmd: reads the on-disk
   token best-effort (absent → empty → loopback gate still covers that case),
   calls BootstrapWithToken, saves credentials, sets auth token on client.
   Both headless paths now go through this single function — no divergence.

2. readPassword bufio fallback removed by accident (REGRESSION)
   Restore the pre-round-1 bufio fallback in readPassword so piped-password
   flows (e.g. pad auth login --interactive in CI) keep working. The bootstrap
   wedge is already prevented by the top-of-promptAndBootstrap TTY guard; the
   generic readPassword fallback is only reached by non-bootstrap callers.

3. Shared core (CLEANUP)
   padInitCmd now calls doHeadlessBootstrap instead of duplicating Bootstrap +
   saveCredentials + SetAuthToken. The --format json asymmetry (init vs setup)
   is resolved by design: pad init is a multi-step flow; for machine-readable
   bootstrap output agents should use `pad auth setup --email … --format json`.
   Documented in the inline comment on the headless branch in padInitCmd.

Tests added: TestHeadlessSetupSendsBootstrapToken, TestHeadlessSetupNoTokenFileOK,
TestReadPasswordFallback. Update internal/cli/bootstrap_test.go for the rename.

* BUG-988 round-2: surface token-read errors, wrap 403 with hint, rescope readPassword test

doHeadlessBootstrap: distinguish os.ErrNotExist (absent token → best-effort
empty, proceed without header) from other read errors (permissions, etc.
→ surface with the file path so operators can diagnose rather than silently
hitting a confusing 403). Wrap 403/forbidden from BootstrapWithToken with an
actionable multi-bullet hint covering loopback gate, token-file path, and
PAD_BYPASS_SETUP_TOKEN.

ReadBootstrapToken (internal/cli/bootstrap.go): add %w to the ErrNotExist
branch so errors.Is(err, os.ErrNotExist) propagates to callers; existing
tests and --cli-prompt hint text preserved.

TestReadPasswordFallback → TestReadPasswordBufioFallback: rescoped to assert
readPassword isolation only; added comment citing BUG-1886 (pre-existing
doInteractiveLogin double-bufio.Reader bug). BUG-1886 filed in docapp.
