- Remove all use slog::* imports and log: slog::Logger fields
- ssh/handle.rs: replace slog macro chains with tracing::{info!, warn!,
error!, debug!}; remove log field from GitSshHandle
- ssh/authz.rs, ssh/mod.rs, ssh/server.rs: remove slog Logger fields
- http/: auth.rs, handler.rs, mod.rs, routes.rs: remove slog usage
- hook/: pool worker, sync modules, webhook_dispatch.rs: remove slog
- pool/worker.rs: only dispatch webhooks after sync succeeds (skip on error);
pass max_retries from PoolConfig to HookWorker
- sync/branch.rs: replaced with stub (sync_refs moved to commit.rs)
- sync/commit.rs: add collect_git_refs() that collects BranchTip/TagTip from
git2 entirely within one sync call; sync_refs now uses owned data so no
git2 types cross .await boundaries (future is Send)
- sync/fsck.rs: remove extraneous "HEAD" arg from rollback git update-ref
(correct syntax is: update-ref -m <msg> <ref> <new-sha> — no old-sha)
- webhook_dispatch.rs: touch_count uses Expr::col().add(1) for atomic
increment instead of overwriting with Expr::value(1)
- pool/mod.rs: pass config.redis_max_retries to HookWorker
