fix: pre-existing test failures across all branches (12 files, 14 tests) #273

Multiple test files fail on every branch (including upstream/main and Brady's dev). These are not regressions from any specific PR — they are pre-existing.

Root Cause Analysis

ENVIRONMENT (2 tests — need Docker)

• test/cli/aspire.test.ts — Docker not installed, tests already have skip guards
• test/aspire-integration.test.ts — Needs Docker + OTel + Playwright

CODE MISMATCH (3 tests — API changed, tests not updated)

• test/otel-provider.test.ts — Module import path or export names changed
• test/hostile-integration.test.ts — Fixture or component API mismatch
• test/cli-shell-comprehensive.test.ts — Coordinator/session API evolved

FLAKY TIMING (7 tests — timeouts too tight)

• test/speed-gates.test.ts — 5s too tight for CLI startup under parallel load
• test/cli-p0-regressions.test.ts — TerminalHarness 5s timeout insufficient
• test/journey-*.test.ts (3 files) — ink-testing-library tick timing races
• test/cli-global.test.ts — Test isolation + timing
• test/upstream-e2e.test.ts — File I/O timing

Proposed Fixes

1. Increase TerminalHarness timeouts from 5s to 10s
2. Increase journey test tick delays from 80ms to 150ms
3. Add skip guards for Docker-dependent tests
4. Fix module import paths in otel-provider tests
5. Verify hostile-integration fixtures exist
