refactor(remote): extract src/remote into @agent-device/remote

[thymikee]

Summary

Moves src/remote (11 production files, 9 tests) into the private @agent-device/remote package with 6 narrow production exports. No behavior change, no root shims. Public agent-device/remote-config is unchanged; the sdk-remote-config tsdown chunk patterns follow the move.

Rebased onto 9ca333d5fb (plugins #3712). RemoteConfigProfile stays declared only in @agent-device/contracts; packages/plugins/src/connection.ts keeps its contracts import, so there is no plugins→remote dependency. 83 files, +250/−145.

Validation

Tested commit: 5fde2314e2 (base 9ca333d5fb), clean worktree, pnpm 11.17.0 (the pinned packageManager).

• pnpm install --frozen-lockfile, pnpm build: exit 0.
• pnpm check:affected --run --head 5fde2314e2, AGENT_DEVICE_VITEST_MAX_WORKERS=1, fail-open full selection (63 checks): 36 passed, 2 deduplicated, 25 skipped as GitHub-authoritative or parked. Exit 0, receipt exactCommit: true.
• An earlier run of this same commit used pnpm 11.21.0 and also passed; the pinned run above replaces it.
• Fresh-context review: no correctness findings. Two low suggestions declined as out of scope for a move: sharing stream-capture.ts through test-kit, and dropping the pre-existing remote-config.ts re-export.

Limits: unit and gate evidence only. CI owns coverage, provider integration and native lanes for this head.

This PR looks ready for review at 45f85df. The move reads as a pure extraction, and all 39 checks pass, with the size report at +61 B installed. Not blocking: the stderr capture in packages/remote/src/tests/upload-progress.test.ts (https://github.com/callstack/agent-device/blob/45f85df/packages/remote/src/__tests__/upload-progress.test.ts#L8) is a hand rewrite of withCapturedStderr, so you could later move stream-capture.ts into @agent-device/test-kit and import it from both sides, and 'remote' could move from TARGET_DAG_RANK to UNRANKED_ZONES in scripts/layering/model.ts (https://github.com/callstack/agent-device/blob/45f85df/scripts/layering/model.ts#L69), as #3706 did for react-native. Take or leave both.

I did not run the build, typecheck or layering gates locally, and I did not inspect the built dist for the sdk-remote-config chunk. I relied on the green CI and your check:affected run. No conflicts. Nothing else blocks it.

The Cubic thread on the sdk-remote-config regexes in tsdown.config.ts no longer applies, because the regexes now match packages/remote/src/remote-config-schema, so please resolve it: #3711 (comment)
