- ServeConfig gains cfg-gated SessionSeam / GitSeam Option fields
(whole-Option struct per seam — the shape decision recorded in the
task notes): unset → the owned rows decline even though the feature
is on, no construction-time validation
- SessionSeam carries the alktty backends map + backend selector +
ownership provider; GitSeam carries the alkgit backend quartet +
caller-owned pipeline semaphore + push_options_negotiated
- optional deps alktty 0.8.1 / alkgit 0.1.0 wired feature-to-dep
(pins verified against crates.io: licenses, MSRV, shared alkcall
resolution); gix-hash 0.28 as dev-dep only (alkgit does not
re-export ObjectId for the trait doubles)
- per-feature construction/unset-declines/Debug rows in config.rs;
accessors session_seam_configured / git_seam_configured; docs state
what each seam handle carries
Verified: cargo test (per-feature + --all-features), clippy ×2
(-D warnings), fmt, cargo doc --no-deps, cargo tree feature isolation
(git-build: no alktty; session-build: no alkgit), taskgraph validate
