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.

Pull request overview
Adds a new Concepts documentation page that explains practical strategies for implementing large/complex features when agent context windows become saturated, and links the page from the documentation table of contents.
Changes:
- Added
docs/concepts/complex-features.mddescribing four approaches to keep/speckit.implementruns within context limits (scoping, delegation, hybrid, and decomposition). - Registered the new Concepts page in
docs/toc.ymlso it appears in the site navigation.

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. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

Summary
Adds a Concepts documentation page describing strategies for handling large or complex features, where context window exhaustion degrades agent performance during
/speckit.implement.This transfers the guideline Manfred shared in discussion #2914 into the docs, as requested in the issue.
