Follow-up to #175: exported-family enumeration returns provenance/path-identity errors as errors instead of an empty family set, so downstream admission reports the real cause instead of a misleading "found 0 families" multi-family rejection. Consumed by PJ4's PR 12b helper.

A dladdr or path-identity failure during exported-family enumeration now
returns its own error instead of folding into an empty family set, so
admission surfaces the real cause rather than a misleading
"found 0 families" rejection.

…ency fixture

RTLD_FIRST hides dependency symbols from dlsym on macOS, so the getter is
cleanly absent there; the provenance error is the Linux shape.

…get (0.24.0)

SDK PR 1b of the parser-extensibility v4 architecture (spec: pj-official-plugins
PR #272), following the core PR (#172, 0.22.0): a second loader for the
already-frozen module ABI — wasmer execution, hardening, and the wasm
authoring target. Ships as its own 0.24.0 release (0.23.0 was taken by the
symbol-provenance fix, #175), so an SDK with the wasm loader is
distinguishable from one without it. Rebased onto main after #174#176: the
budget-aware NativeParserModule::load keeps #175's defining-object symbol
provenance, and the docs no longer describe wasm as unavailable.

- wasmer 7.0.1 statically linked (pinned; required only by the plugin_host
  component — plugin_sdk consumers stay wasmer-free). Exit-criterion prototype
  findings encoded in the loader contract: the pinned static lib exports no
  wasm_module_share/obtain symbols (engine-owned module reuse: one compilation,
  store-per-bound-instance with isolated state) and no creator-thread affinity
  exists — calls are sequential-only, host-serialized. Pin re-evaluated against
  7.2.1: no C-API gains, WASI-syscall CVEs unreachable under the empty import
  allow-list, and 7.2 drops x86_64-darwin (rationale in ARCHITECTURE.md)
- wasm loader: validation before any instantiation — manifest custom section
  via the shared codec (exactly one), reactor model enforced (_initialize
  required, start section/_start rejected), operational export set verified
  by name AND signature through the shared pj_base wasm inspector, and a
  frozen EMPTY import allow-list (a parser module may import nothing)
- execution runtime: metered store-per-instance calls (the pinned lib exports
  the wasmer_metering_* C API but no interrupt/epoch/deadline surface, so
  limits are enforceable instruction metering — fresh point allowance per
  guest call, exhaustion = distinct contract violation), linear-memory base
  re-acquired at every point of use with overflow-safe bounds, splices
  resolved against the original host payload, shared fault taxonomy + strike
  tracker with quarantine replay
- memory caps at validation: artifacts must declare a linear-memory maximum
  (default cap 256 MiB); the engine enforces it at runtime. Aggregate session
  budgets (modules, artifact size, claims, active instances, declared memory)
  gate admission with DECLINE and mutate nothing on rejection
- adversarial fixtures: unreachable trap, metered infinite loop, memory-growth
  bomb, admission limits, quarantine replay — plus the M1 rejection matrix
- pj-wasm-embed-manifest installed CLI (embed/verify) wrapping the shared
  section codec; pj_add_parser_module(... TARGETS native wasm) builds both
  artifacts from one source with post-link audit, dogfooded on the toy module
- fix: release the metering middleware on the adapter-failure path
- VERSION 0.24.0, CHANGELOG entry, CI wasmer job (metering-symbol check)

Tests: 80/80 Debug+ASAN with both toolchain roots; graceful skip verified for
each root independently.
