houseme cd327c81f5 fix(targets): harden control-plane, TLS reload, and runtime extension points (#4504)
Addresses security/correctness audit findings in the target-plugin control
plane, TLS reload coordinator, and runtime extension registries.

control_plane (backlog#977):
- Install now preserves the currently installed revision as previous_revision
  so Rollback actually restores the prior version instead of a no-op.
- Split the gate: circuit-breaker and runtime-activation checks apply only to
  Install/Enable; Disable and Rollback stay available as break-glass
  remediation while the breaker is open.
- Enforce the sidecar runtime protocol version for every external transport
  (previously skippable by declaring a non-gRPC transport) and validate the
  plugin api_compatibility_version at planning time.
- Download/signature/provenance host allowlisting now matches the full
  host authority, so an allowlisted host never implicitly authorizes a
  different host:port.

TLS reload coordinator/validate (backlog#981, #970-coordinator):
- Compute the fingerprint before building material in register() to remove the
  TOCTOU that could permanently pin an old certificate; rotation self-heals.
- Always start a detection loop when reload is enabled; Watch mode no longer
  returns success without any loop.
- validate_cert_key_pairing now verifies the private key matches the
  certificate's public key instead of only parsing both files.
- Normalize a zero poll interval to a positive minimum to avoid a panic that
  silently killed the poll loop.
- Serialize reload cycles with a per-target mutex; a first-step fingerprint
  read failure now records last_error and a failure metric.
- Duplicate label registration stops and joins the previous loop before
  publishing the replacement (stop-before-start), preventing orphaned loops.

runtime extension points (backlog#983 runtime subset):
- ops_profiler/ops_diagnostics authorize before probing the registry so an
  unauthorized caller cannot learn whether a backend/surface exists.
- s3_hooks dispatch_post_auth actually traverses the registered hooks for the
  point instead of unconditionally returning Continue.
- sidecar send_with_timeout redacts errors and uses the configurable failure
  threshold via policy, and a successful send resets the breaker accounting.
