feat(dolt): add federation prototype tests
Add integration tests validating Dolt APIs needed for peer-to-peer federation between Gas Towns: - TestFederationDatabaseIsolation: verify separate towns have isolated DBs - TestFederationVersionControlAPIs: branch, checkout, merge, commit - TestFederationRemoteConfiguration: AddRemote accepts dolthub:// URLs - TestFederationHistoryQueries: commit history, dolt_log, AS OF Key finding: Production federation uses dolt sql-server remotesapi (port 8080) for direct peer-to-peer push/pull - no DoltHub required. Also fixes concurrent_test.go Merge() return value handling. Refs: bd-wkumz (Federation epic), hq-ew1mbr.7 (prototype task) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>

// These tests validate the Dolt APIs needed for federation between towns.
|

// Production federation uses hosted Dolt remotes (DoltHub, S3, etc.), not file://.
|
||||
//
|
||||
// What we can test locally:
|
||||
// 1. Database isolation between towns (separate Dolt databases)
|
||||
// 2. Version control APIs (commit, branch, merge)
|
||||
// 3. Remote configuration APIs (AddRemote)
|
||||
// 4. History and diff queries
|
||||
//
|
||||
// What requires hosted infrastructure:
|
||||
// 1. Actual push/pull between towns (needs DoltHub or dolt sql-server)
|
||||
// 2. Cross-town sync via DOLT_FETCH/DOLT_PUSH
|
||||
// 3. Federation message exchange
|

//
