* feat(core): add git-backed memory repos and block manager
Introduce a GCS-backed git repository per agent as the source of truth for core
memory blocks. Add a GitEnabledBlockManager that writes block updates to git and
syncs values back into Postgres as a cache.
Default newly-created memory repos to the `main` branch.

* feat(core): serve memory repos over git smart HTTP
Run dulwich's WSGI HTTPGitApplication on a local sidecar port and proxy
/v1/git/* through FastAPI to support git clone/fetch/push directly against
GCS-backed memory repos.

* fix(core): create memory repos on demand and stabilize git HTTP
- Ensure MemoryRepoManager creates the git repo on first write (instead of 500ing)
and avoids rewriting history by only auto-creating on FileNotFoundError.
- Simplify dulwich-thread async execution and auto-create empty repos on first
git clone.

* fix(core): make dulwich optional for CI installs
Guard dulwich imports in the git smart HTTP router so the core server can boot
(and CI tests can run) without installing the memory-repo extra.

* fix(core): guard git HTTP WSGI init when dulwich missing
Avoid instantiating dulwich's HTTPGitApplication at import time when dulwich
isn't installed (common in CI installs).

* fix(core): avoid masking send_message errors in finally
Initialize `result` before the agent loop so error paths (e.g. approval
validation) don't raise UnboundLocalError in the run-tracking finally block.

* fix(core): stop event loop watchdog on FastAPI shutdown
Ensure the EventLoopWatchdog thread is stopped during FastAPI lifespan
shutdown to avoid daemon threads logging during interpreter teardown (seen in CI
unit tests).

* fix(core): backfill git memory repo when tag added
When an agent is updated to include the git-memory-enabled tag, ensure the
git-backed memory repo is created and initialized from the agent's current
blocks. Also support configuring the memory repo object store via
LETTA_OBJECT_STORE_URI.

* fix(core): preserve block tags on git-enabled updates
When updating a block for a git-memory-enabled agent, keep block tags in sync
with PostgreSQL (tags are not currently stored in the git repo).

* feat: add provider trace backend abstraction for multi-backend telemetry
Introduces a pluggable backend system for provider traces:
- Base class with async/sync create and read interfaces
- PostgreSQL backend (existing behavior)
- ClickHouse backend (via OTEL instrumentation)
- Socket backend (writes to Unix socket for crouton sidecar)
- Factory for instantiating backends from config
Refactors TelemetryManager to use backends with support for:
- Multi-backend writes (concurrent via asyncio.gather)
- Primary backend for reads (first in config list)
- Graceful error handling per backend
Config: LETTA_TELEMETRY_PROVIDER_TRACE_BACKEND (comma-separated)
Example: "postgres,socket" for dual-write to Postgres and crouton

* feat: add protocol version to socket backend records
Adds PROTOCOL_VERSION constant to socket backend:
- Included in every telemetry record sent to crouton
- Must match ProtocolVersion in apps/crouton/main.go
- Enables crouton to detect and reject incompatible messages

* fix: remove organization_id from ProviderTraceCreate calls
The organization_id is now handled via the actor parameter in the
telemetry manager, not through ProviderTraceCreate schema. This fixes
validation errors after changing ProviderTraceCreate to inherit from
BaseProviderTrace which forbids extra fields.
