* feat: repo-scoped dynamic sandbox snapshots
Let admins build a per-repo sandbox image from a custom Dockerfile so runs
targeting that repo boot from a snapshot with its deps pre-baked. Snapshot
selection is purely additive: repos without a `ready` repo-scoped snapshot
always fall back to the configured DEFAULT_SANDBOX_SNAPSHOT_ID.
Backend adds a repo_snapshots store module (Dockerfile + build status keyed by
owner/name), threads the resolved repo through the LangSmith sandbox creation
path, runs builds via SandboxClient.create_snapshot_from_dockerfile in a
throwaway builder sandbox, and exposes admin-only CRUD + build endpoints. The
UI adds an admin-only Agents-tab page (repo picker + Monaco Dockerfile editor +
build status/logs).

* fix: harden repo snapshot builds
Require REPO_SNAPSHOT_BASE_IMAGE for generated Dockerfile templates so admins
cannot accidentally build a repo snapshot from a bare Python image that lacks
Open SWE's sandbox tools. Allow stale building records to be retried by tracking
build_started_at and treating old or missing timestamps as stale.

* fix: document repo snapshot base image config
Document REPO_SNAPSHOT_BASE_IMAGE alongside sandbox snapshot setup and convert
missing base-image configuration into a handled dashboard API error so admins see
a clear configuration message instead of an unhandled template-generation error.

* feat: per-repo custom instructions for the coding agent
Adds per-repository custom instructions for the main coding agent,
mirroring the reviewer's per-repo style prompts. Instructions are stored
in the LangGraph Store, managed via dashboard API + UI (Monaco editor),
and appended to the agent's system prompt for runs targeting that repo.
