Comment:import-fossil --submanifest: drop the whole-history replay gate and --force

The gate replayed every commit through the from-scratch tree builder three times to predict what the conversion itself measures, and on pkgsrc that was 14 of 26 hours before a byte was written. The conversion writes a new project beside an untouched source, so the honest evidence is the converted store: the summary now reports its bytes against the flat source's. The partition parameter comes from --k or the tip sweep; a history no k partitions is refused, as 'submanifest enable' refuses it. 'zit submanifest analyze --replay-all' keeps the model for anyone who wants it first. Closes zit#129.

submanifest convert, and import-fossil --submanifest straight from a fossil URL

The rebirth arm of import-fossil required a zit store, so the verb that says 'import a fossil' could not take one. It now accepts the fossil's sync URL like --compatible does, cloning a transient flat store beside DIR and removing it after; a local store stays accepted. The zit->zit conversion gets its proper home as 'zit submanifest convert SRC DEST', beside 'enable', which now says what it does not do: existing check-ins stay flat, and fossil peers receive nothing new from the next commit. Diagnostics carry the verb the operator typed. Closes zit#168. check-in: abd850dc4c user: dmestas tags: trunk

import-fossil --submanifest: build each check-in's tree from its parent's with the sub-manifest editor

Every check-in went through artifact.buildTree from scratch, so a wide tree cost its whole file set per commit against a few changed slices actually written. The converter now applies each check-in's change set over its primary parent's root with TreeEditor — the commit verb's builder — keeps a parent cache released as children consume it, interns the retained cards, runs the pair proof through the run-scoped flatten memo, and parses each source manifest once. The Git importer's LogTreeStore moves to a shared module. Output is unchanged: every check-in hash matches the from-scratch build on libfossil and on a 30k-file synthetic history.
