* feat: optional separate LangSmith key/endpoint for sandboxes
Adds optional SANDBOX_LANGSMITH_API_KEY / SANDBOX_LANGSMITH_ENDPOINT env
overrides so sandboxes can run against a different LangSmith workspace than
the one used for tracing and other API calls. Both fall back to the existing
LANGSMITH_API_KEY / LANGSMITH_ENDPOINT resolution, so default behavior is
unchanged.
Applied to sandbox create/connect/delete, the GitHub proxy config, and repo
snapshot builds.
* feat: name langsmith sandboxes openswe-<b32(thread id)>
New sandboxes get a deterministic, thread-traceable name derived from the
LangGraph thread id (UUID base32-encoded lowercase, no padding), e.g.
openswe-ci2fm6asgrlhqerukz4bencwpa. Falls back to an unset name when no thread
id is present. Reconnect/delete still key off the server-assigned sandbox id.
* fix: pass sandbox base URL (root + /v2/sandboxes) to langsmith SDK clients
The SDK's api_endpoint is the sandbox base, not the API root — its methods
append /boxes, /snapshots, etc. Passing the bare root sent calls to
<root>/boxes instead of <root>/v2/sandboxes/boxes. Add _get_sandbox_api_endpoint
for the SDK clients (async client, provider, snapshot SandboxClient) while the
proxy-config PATCH keeps using the root.

Part of the domain-reorg adoption (build plan step C1): fork content,
upstream layout. Moves INSTALLATION.md/CUSTOMIZATION.md under docs/,
static/ under assets/, and default_prompt.md under agent/resources/
(packaged via agent/resources/__init__.py), then switches prompt.py's
loader to importlib.resources with an explicit DEFAULT_PROMPT_PATH
override, matching upstream's hunk. README and CUSTOMIZATION.md links
updated for the new paths; wheel build verified to still ship
agent/resources/default_prompt.md.
