* 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).

* chore(core): remove send_*_message_to_agent from SyncServer
Drop send_message_to_agent and send_group_message_to_agent from SyncServer and
route internal fire-and-forget messaging through send_messages helpers instead.

* 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 tags support to blocks
* fix: add timestamps and org scoping to blocks_tags
Addresses PR feedback:
1. Migration: Added timestamps (created_at, updated_at), soft delete
(is_deleted), audit fields (_created_by_id, _last_updated_by_id),
and organization_id to blocks_tags table for filtering support.
Follows SQLite baseline pattern (composite PK of block_id+tag, no
separate id column) to avoid insert failures.
2. ORM: Relationship already correct with lazy="raise" to prevent
implicit joins and passive_deletes=True for efficient CASCADE deletes.
3. Schema: Changed normalize_tags() from Any to dict for type safety.
4. SQLite: Added blocks_tags to SQLite baseline schema to prevent
table-not-found errors.
5. Code: Updated all tag row inserts to include organization_id.

* fix: add ORM columns and update SQLite baseline for blocks_tags
Fixes test failures (CompileError: Unconsumed column names: organization_id):
1. ORM: Added organization_id, timestamps, audit fields to BlocksTags
ORM model to match database schema from migrations.
2. SQLite baseline: Added full column set to blocks_tags (organization_id,
timestamps, audit fields) to match PostgreSQL schema.
3. Test: Added 'tags' to expected Block schema fields.
This ensures SQLite and PostgreSQL have matching schemas and the ORM
can consume all columns that the code inserts.

* revert change to existing alembic migration
* fix: remove passive_deletes and SQLite support for blocks_tags
1. Removed passive_deletes=True from Block.tags relationship to match
AgentsTags pattern (neither have ondelete CASCADE in DB schema).
2. Removed SQLite branch from _replace_block_pivot_rows_async since
blocks_tags table is PostgreSQL-only (migration skips SQLite).

Swap the order of @trace_method and @raise_on_invalid_id decorators
across all service managers so that @trace_method is always the first
wrapper applied to the function (positioned directly above the method).
This ensures the ID validation happens before tracing begins, which is
the intended execution order.
