chore: bump version to 0.4.0

[galligan]

Context

Bumps outfitter-dispatch to 0.4.0 after the stable refs / flat CLI work landed on main via PR #33.

What changed

• Updated the project version in pyproject.toml from 0.3.0 to 0.4.0.
• Updated the editable package entry in uv.lock to match.

How to test

• uv run dispatch --version -> dispatch 0.4.0
• just check -> 190 passed, 9 deselected, build and package contents check passed, and dist/outfitter_dispatch-0.4.0.* was built.
• Live dispatch smoke with isolated DISPATCH_HOME:
  • dispatch new created a real managed Codex thread on gpt-5.3-codex-spark.
  • The worker ran UV_CACHE_DIR=/tmp/dispatch-smoke-uv-cache uv run dispatch --version and observed dispatch 0.4.0.
  • The worker confirmed dispatch schema send includes ref, id, title, and managed in the output schema.
  • dispatch send follow-up returned the identity-rich ActionAck, and the worker replied via dispatch tail.

Risks / notes

• The first read-only live smoke could not run uv run because UV needed a writable cache, then fell back to the older globally installed dispatch 0.2.1. The successful smoke used workspace-write only to permit a temp UV cache; no repo files were changed by the smoke worker.
• Both smoke threads were archived after verification.
