Temporarily deprecate workflow support (#23)

[willwebster5]

Summary

Temporarily deprecates talonctl workflow support so the tool stops crashing on workflows, while preserving the provider code for a future tested rewrite. Addresses the immediate breakage in #23.

Why

The workflow provider was non-functional (verified against FalconPy Workflows v1.6.1):

• apply_delete called delete_definition(...) — no delete method exists on the Workflows class; the CrowdStrike Workflows API does not expose workflow-definition deletion.
• requires_replacement() forced REPLACE (delete + recreate) for every change and apply_update() hard-raised — so with no delete, no workflow change was deployable; apply crashed mid-wave.
• _fetch_all_remote_workflows called get_definitions(...) — also non-existent → sync/drift raised AttributeError. (search_definitions already returns full models, so that batch loop was never needed.)
• update_definition exists but 500s on a naive compiled-model round-trip; the correct payload shape is unknown and can't be validated without live-tenant access.

A partial-but-crashing provider is worse than an honestly-unavailable one, hence temporary deprecation rather than a rushed, untestable fix.

What changed

• Discovery (template_discovery.py): "workflow" moved to a new DEPRECATED_RESOURCE_TYPES. Workflow templates are still scanned, emit a clear deprecation warning, and are excluded from results — so no "workflow" key reaches validate/plan/apply/sync/drift.
• Provider dispatch (provider_adapter.py): workflow provider unregistered.
• Drift: "workflow" removed from FETCHABLE_TYPES.
• init: no longer scaffolds resources/workflows/.
• Provider + example kept with deprecation notices documenting the exact API findings for a future rewrite.
• Docs: README/CLAUDE.md "seven → six" resource types, CHANGELOG entry, provider docs.

Behavior after this change

A project that still contains workflow templates gets a one-time warning and the templates are ignored; all other resource types proceed normally. No command crashes — even with an explicit --resources=workflow (downstream consumers all use .get() / iterate discovered results).

WARNING ... workflow support is temporarily deprecated (see issue #23) — workflow template(s) will be ignored by validate/plan/apply/sync/drift.
workflow in results: False

Testing

• pytest tests/ — 799 passed; ruff format --check . and ruff check . clean.
• New discovery test asserts workflow templates warn + are excluded.
• Removed two tests that mocked non-existent SDK methods (get_definitions, delete_definition) — they passed only via Mock auto-attributes, codifying the bug.
• This environment has no live NGSIEM API access, so all changes were verified offline.

Not in scope

A working update path (needs live-tenant testing of the update_definition 500 and possibly a CrowdStrike support ticket) and disable-as-destroy semantics via workflow_definition_action — these belong to the future un-deprecation work.
