* feat(#1213): Capability State Writer — write-side inverse of the resolver
Adds src/capability-writer.cts (setCapabilityState + cmdCapabilitySet) and the
`gsd-tools capability set` subcommand: the write-side inverse of the capability
resolver (ADR-1213). One desired capability state projects onto the substrates —
`enabled` drives the runtime surface (canonical on/off), `gates` drive federated
config keys (hook granularity), install profile is a read-only floor — then
re-resolves and reports divergence (assert-and-report), so "off means off" holds
as a write-time invariant. Adds batched setConfigValues; routes gsd:settings
capability hook-gates through the writer. Docs: CLI-TOOLS reference, how-to,
ADR-1213, CONTEXT.md term.
