Mechanical rename produced by scripts/msd-rename.cjs: gsd/Gsd/GSD -> msd/Msd/MSD
across contents and paths, upstream package/repo coordinates -> @golem15/msd-core
and golem15com/msd-core. Deep links into upstream history, sibling upstream
packages, the GSD-2 import feature, CHANGELOG.md and .changeset/ are kept as-is.
Hand edits on top: MSD block-letter banner and logos, LICENSE copyright line,
package/plugin identity, regenerated lockfile, install-tree fixtures, derived
registries and benchmark baseline; migration checksum baseline re-locked
(MSD keeps its own install state, so no install had applied the old sums);
sort-order and regex-escaped expectations in tests adjusted.
Core half of #1105: a legal external_job_waiting deferred state so an async-dispatched Execute step (committing a .planning/async-jobs/<job>.json manifest, deferring SUMMARY.md) is not an illegal partial. execute-phase safe-resume, resume-project, and pause-work reconcile against the versioned scheduler-agnostic manifest stability contract without re-dispatching; the producer is the capability half (#1164). Closes#1165.
