fix(sdlc): persist branch metadata on main before feature branch creation

The `sdlc merge` command reads the Branch field from the feature manifest
on main, but `sdlc branch create` was only committing that state to the
feature branch (via the executor's CommitAndPush). This caused merge to
fail with "feature has no branch".

Two changes:
1. cmd/sdlc/cmd_branch.go: commit .sdlc/ state to main before
   `git checkout -b`, ensuring Branch metadata is on main where merge
   reads it.
2. internal/worker/sdlc_executor.go: reset workspace to main
   (`git fetch && git checkout main && git reset --hard origin/main`)
   before each SDLC task, preventing cross-task branch contamination
   from commands that switch branches.

Also updates foundary cookbook with architect fallback pattern and
on_error: continue for steps that may fail during early lifecycle.
