* docs: add guide for handling complex features
Add a Concepts page documenting strategies for dealing with large or
complex features where context window exhaustion degrades agent
performance during implementation. Covers limiting tasks per run,
sub-agent delegation, combining both, and decomposing into smaller
specs, with a guideline table for choosing an approach.
Closes#2986

* docs: address review feedback on complex features guide
Use task IDs (T001-T010) instead of bare numbers to match the tasks.md
template format, and add the combined scoping + delegation approach to
the selection table for completeness.
