vhaudiquet 6a5c5a7106 context: fix deadlock and panics when resolving parented contexts
set_current held the config RwLock for writing across make_context,
which for a context with a parent re-entered the same lock through
Context::new's global-manager lookup, deadlocking 'pkh context use'.
Context building is now lock-free by construction: make_context
resolves parent chains against a snapshot map (also rejecting parent
cycles), and neither set_current nor remove_context holds a guard
while building a Context.

A corrupt contexts.json no longer aborts every command at manager
init: load falls back to the default local-only config, backs the
corrupt file up to contexts.json.bak so a later save cannot silently
destroy it, and a dangling current/parent context falls back to local
with an error log instead of panicking.

vhaudiquet 592e98c1e9 deb: pass the build context explicitly instead of swapping the global
build_binary_package installed its ephemeral chroot context into the
process-global manager and read it back with context::current(),
ignoring its ctx parameter: two concurrent builds would re-point each
other's global and each drop would clean up whichever chroot was
current at the time. The guard now keeps the Arc of the context it
created (parented directly on the base context, not on a config-name
lookup), exposes it via context(), and Drop cleans up exactly that
context and restores the exact handle that was current at creation,
so overlapping builds no longer cross-destroy each other.

vhaudiquetandvhaudiquet 1538e9ee19 deb: cross-compilation, ephemeral contexts, local builds
CI / build (push) Successful in 7m18s
Multiple changes:
- New contexts (schroot, unshare)
- Cross-building quirks, with ephemeral contexts and repositories management
- Contexts with parents, global context manager, better lifetime handling
- Local building of binary packages
- Pull: pulling dsc files by default
- Many small bugfixes and changes

vhaudiquet 1d65d1ce31 context: add context
CI / build (push) Successful in 1m50s
pkh context allows to manage contexts (local, ssh) and run contextualized commands (deb)

in other words, this allows building binary packages over ssh
