docs: fix stale/broken architecture doc references after crate extraction

Several architecture docs pointed at source paths that moved during the
homeboy-error / homeboy-engine-primitives crate extraction and the
cli_surface directory split:

- error 'Centralized error system' -> crates/homeboy-error/src/lib.rs
- template system -> crates/homeboy-engine-primitives/src/template.rs
- CapturedOutput primitive -> crates/homeboy-engine-primitives/src/command.rs
- output parse primitive -> crates/homeboy-engine-primitives/src/output_parse.rs
- src/cli_surface.rs -> src/cli_surface/ (now a directory)
- project/component/overrides.rs -> src/core/project/component/overrides.rs

Each updated reference notes the stable re-export path where relevant so
readers (and agents) can still resolve the concept via crate::core::*.

Clears 4 stale_doc_reference and 3 broken_doc_reference findings. The two
remaining fuzz.md 'broken directory' findings are detector false
positives (prose describing runtime/naming-convention dirs, not repo
paths) tracked in #8343.

 No migration or deprecation warning is included in this slice because the serialized config contract is intentionally identical. The remaining removals above require a migration/warning phase before deleting currently accepted config locations.
