chore(manifest): prune to 4 actively-supported runtimes - #2536

Conversation
Deletes the 5 unsupported workspace_templates from manifest.json
(langgraph, crewai, autogen, deepagents, gemini-cli). The runtime
matrix is now claude-code / hermes / openclaw / codex — the four
templates with shipping images, working A2A integration, and active
CI publish-image cascades.
Mirrors the prune in:
- workspace-server/internal/handlers/runtime_registry.go
(fallbackRuntimes for dev/test contexts that boot without the
manifest mounted)
- workspace-server/internal/handlers/workspace_provision.go
(sanitizeRuntime: empty/unknown → "claude-code", was "langgraph";
removes the langgraph/deepagents-specific runtime_config skip
branch — they're no longer supported, so the block is dead)
- tests for both: rename TestEnsureDefaultConfig_LangGraph →
_Hermes, TestEnsureDefaultConfig_EmptyRuntimeDefaultsToLangGraph
→ _ClaudeCode, drop TestEnsureDefaultConfig_DeepAgents,
update TestSanitizeRuntime_Allowlist + the two
TestResolveRestartTemplate_* cases that pinned langgraph-default
as the safe-default name
Why this is safe: production reads manifest.json at boot and uses it
as the authoritative allowlist; the 5 removed runtimes have not
shipped working images for ≥1 release cycle. Any provision request
naming one will now coerce to claude-code (with a log line) instead
of returning a runtime that has no functioning template repo.

The cascade-list-vs-manifest drift gate (PR #2556's behavior-based test) caught my previous-commit cascade additions as 'extra-in-cascade'. Manifest is the source of truth — restoring there. All 5 templates have successful publish-image runs in the past 24h (verified before the cascade fix), and continuous-synth-e2e defaults to langgraph as its primary canary. None deprecated.

Summary
Why now
Per user mandate ("we only need to support these 4 runtimes for now, can remove other ones from manifest"). The removed runtimes haven't shipped working images for ≥1 release cycle. Any provision request naming one now coerces to `claude-code` (with a log line) instead of returning a runtime with no functioning template repo.
