A build seat's capacity follows its CPU share and its build hours; asks say their phases (issues 1890, 1806) #100

Group fix/capacity-follows-cpu-share (mesh-sdk, mesh-catalog, mesh-delivery). mesh-sdk merges first; the other two pin this head (805b4d9, which merges sdk main #99 into the branch).

Capacity = min(configured, the build slice's CPU quota cores / cores-per-step), read live from the cgroup, said when it changes and written to capacity..
Build hours (the operator, 2026-10-26 21:18: g14 builds only 18:00-06:00): optional build-hours per node in local time; outside it capacity is 0, running steps finish, one timer to the next edge, each edge said once; an unreadable value means any hour, shown loudly.
A running ask writes its phases to its step key.

Quick fix: lower each node's configured capacity by hand. Thorough fix (chosen): capacity derived from what the node gives the build slice, in the shared puller every build module uses.

No try (one release, one check): this group's check is its only run.

A build seat's capacity follows its node's build CPU, and a running ask says its phases 02f50bd9d6

Since the build CPU cap (issue 1806) shanks' mesh-build-go kept capacity 3 inside a 12-core slice:
three full checks got about 4 cores each and ran past the 30-minute step bound (issue 1890).
The puller now judges by min(configured, floor(slice quota cores / cores-per-step)), the quota
read live from its cgroup, says it on change and writes capacity.<node> to the pauses state.
A run's phases (fetch and merge, digest, tests) are logged with the ask id and written to its
running step key; Asker.Wait hands every step value to a WithStepSeen hook.

A build module takes asks only within its node's build hours

The operator, 2026-10-26 21:18: g14 builds only from 18:00 to 06:00. A build-hours setting names a
window per node in its local time (crossing midnight allowed, absent = any hour); outside it the
capacity judged by is 0, running steps finish, and the puller wakes on one timer at the next edge.
The change is said in the log and in capacity.<node> with the window and when it opens.
