chore(sdk): bump agent-trajectories to ^0.5.4

The unification in 95eafc4 relied on looser types from
agent-trajectories (role as open string, expanded TrajectoryEventType,
relaxed id regex). Those types only existed locally on fix/reconcile-stale-index
when the worker implemented the PR, so CI (which installs from npm)
hit 5 TS errors against the published 0.5.3.

agent-trajectories@0.5.4 is now published with those looser types
(AgentWorkforce/trajectories#22). Bumping:
  - packages/sdk/package.json: ^0.5.3 -> ^0.5.4
  - root package.json (devDependencies): ^0.4.1 -> ^0.5.4
  - package-lock.json regenerated via `npm install --package-lock-only`

Verified locally:
  - `npm run build` in packages/sdk: clean tsc -p tsconfig.build.json
  - `npx vitest run src/__tests__/workflow-trajectory.test.ts`: 31 passed

This should turn CI green on PR #732.
