v0.3.0-beta | Fix: Resolved Crawler "Context Deadline Exceeded" Cascading Failures

• Removed the global 10-minute timeout constraint applied to the BootScan execution during both CLI initialization (cmd/loa/main.go) and server startup (internal/server/server.go).
• Replaced context.WithTimeout with context.WithCancel, allowing the crawler to process large codebases indefinitely without aborting the parent context.
• Individual LLM inference requests continue to respect a strict per-request timeout via the internal http.Client, ensuring stalled connections are handled gracefully without prematurely terminating the entire indexing loop.
