Implements the invocation and management surfaces from
plans/custom-commands-design.md §4 and §6:
- Top-level dispatch: an enabled macro <name> now runs as ".<name> [args]"
from the command catch-all; runtime-disabled macros point at
".macro enable <name>", locked macros name the owning config, and
unknown commands keep the existing error verbatim
- .macro enable|disable <name>: runtime toggles over the in-memory
global-level enabled_macros list (disable with no list materializes
all-active-minus-name); toggles error when a role/agent/session
allowlist owns the field
- .set enabled_macros <csv|null> with workspace-then-global existence
validation; .set key completion gains enabled_macros and the
previously missing enabled_skills
- Dynamic completion: enabled macros (with descriptions) join built-ins
on ".<TAB>" without touching the static command registry;
".macro <TAB>" lists invocable macros (incl. built-in-shadowed ones)
plus the enable/disable subcommands; second-arg completion offers
toggle-eligible names
- .list macros: enriched table (name, source, isolated, state,
description) covering every resolver state incl. missing and
shadowed rows; .help gains a custom-commands section
- Session info/render and sysinfo display enabled_macros; Macro::load
resolves workspace-then-global; enable/disable rejected as macro
names in the creator
