Cyber MacGeddon 1fc0d8f192 feat: pluggable bootstrap framework with ordered initialisers
Replaces the previous pair of single-purpose bootstrap processors
(config_bootstrap + pulsar_bootstrap) with a generic Bootstrapper
that runs a configurable list of pluggable "initialisers" in a
reconciliation loop.

Design
------
See docs/tech-specs/bootstrap.md for the full spec.

The bootstrapper is a single AsyncProcessor that:

  * Reads a list of initialiser specifications (class, name, flag,
    params) from either a direct `initialisers` parameter
    (processor-group embedding) or a YAML/JSON file (`-c`, CLI).
  * On each wake, runs a cheap service-gate (config-svc + flow-svc
    round-trips), then iterates the initialiser list, running each
    whose configured flag differs from the one stored in
    __system__/init-state/<name>.
  * Stores per-initialiser completion state in the reserved
    __system__ workspace; services never see these keys because of
    the _-prefix notification filter.
  * Adapts cadence: ~5s on gate failure, ~15s while converging,
    ~300s in steady state.
  * Isolates failures — one initialiser's exception does not block
    others in the same cycle; the failed one retries next wake.

Initialiser contract
--------------------
  * Subclass trustgraph.bootstrap.base.Initialiser.
  * Implement async run(ctx, old_flag, new_flag).
  * Opt out of the service gate with class attr
    wait_for_services=False (only used by PulsarTopology — config-svc
    cannot come up until Pulsar namespaces exist).
  * ctx carries short-lived config and flow-svc clients plus a
    scoped logger.

Core initialisers (trustgraph.bootstrap.initialisers.*)
-------------------------------------------------------
  * PulsarTopology     — creates Pulsar tenant + namespaces
                         (pre-gate, blocking HTTP offloaded to
                          executor).
  * TemplateSeed       — seeds __template__ from an external JSON
                         file; re-run is upsert-missing by default,
                         overwrite-all opt-in.
  * WorkspaceInit      — populates a named workspace from either
                         __template__ (with an explicit types list)
                         or a seed file; raises cleanly if the
                         template isn't seeded yet (retries on
                         next cycle).
  * DefaultFlowStart   — starts a specific flow in a workspace;
                         no-ops if the flow is already running.

Enterprise or third-party initialisers plug in via fully-qualified
dotted class paths in the bootstrapper's configuration — no core
code change required.

pyproject.toml
--------------
  * Replaces config-bootstrap + pulsar-bootstrap entries with a
    single `bootstrap` script pointing at the new Processor.
