feat(shell): auto-pull .docker-git state on docker-git startup

[konard]

Summary

• Performs git pull --rebase on the ~/.docker-git directory every time the docker-git CLI is invoked, ensuring local state is always up-to-date with the remote repository before any command runs
• Adds autoPullState effect to state-repo.ts that pulls with GitHub auth when available and silently logs warnings on failure (never blocks CLI execution)
• Controllable via DOCKER_GIT_STATE_AUTO_PULL env var (enabled by default when origin remote exists, can be disabled with false/0/off)
• Extracts shared isFeatureEnabled predicate to deduplicate auto-pull and auto-sync env logic

Математические гарантии

Инварианты:

• ∀ invocation ∈ docker-git: autoPull(~/.docker-git) *> handle(command)
• ∀ error ∈ PullErrors: error → logWarning(error) ∧ ¬fail(program)

Предусловия:

• ~/.docker-git is a git repo with origin remote (otherwise auto-pull is skipped)

Постусловия:

• ∃ state: pulled(~/.docker-git) ∨ warned(error)
• CLI command execution is never blocked by auto-pull failures

Сложность:

• Время: O(1) network round-trip for git pull --rebase
• Память: O(1) — no additional data structures

Test plan

• Unit tests for isAutoPullEnabled env predicate (truthy/falsy/undefined/empty values)
• Integration test: pulls new commits from remote into .docker-git
• Integration test: does nothing when .docker-git is not a git repo
• Integration test: does nothing when .docker-git has no origin remote
• Integration test: respects DOCKER_GIT_STATE_AUTO_PULL=false to skip pull
• Integration test: does not fail when .docker-git directory does not exist
• All 117 tests pass (35 test files)
• Lint passes
• Typecheck passes

Closes #178
