* add self compaction method with proper caching (pass in tools, don't refresh sys prompt beforehand) + sliding fallback
* updated prompts for self compaction
* add tests for self, self_sliding_window modes and w/o refresh messages before compaction
* add cache logging to summarization
* better handling to prevent agent from continuing convo on self modes
* if mode changes via summarize endpoint, will use default prompt for the new mode

* 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).

The per_file_view_window_char_limit column is defined as INTEGER (32-bit)
in PostgreSQL. Without API-level validation, users could pass values
exceeding int32 max (2,147,483,647), causing database errors.
Changes:
- Added MAX_INT32, MAX_PER_FILE_VIEW_WINDOW_CHAR_LIMIT, and
MAX_FILES_OPEN_LIMIT constants
- Added field validators to CreateAgent and UpdateAgent schemas to
enforce these limits
