TigahandGitHub 1b41b5ed65 feat(modules): add ignition, profiler and heapdump exposure modules (#196)
modules/recon/laravel-ignition-exposure.yaml probes the live
/_ignition/health-check endpoint and extracts can_execute_commands, the flag
that marks the CVE-2021-3129 remote code execution surface. this is an active
probe, complementary to the version based ignition entry in the framework cve
map.

modules/recon/symfony-profiler-exposure.yaml flags an exposed web profiler on
its structural markers and extracts a request token to pivot to a captured
request.

modules/recon/spring-heapdump-exposure.yaml flags an exposed actuator heap
dump on the hprof magic anchored at the start of the body, which a json marker
module cannot see because the dump is binary, and extracts the hprof version.
the anchor keeps a page that merely quotes the magic from matching.

internal/modules/debug_exposure_test.go drives the three modules end to end
through ExecuteHTTPModule and asserts the leak alongside the near misses a
strict review wants pinned: a prose mention of ignition, the hprof magic away
from the start, a plain 200 body and a 404, none of which may match, plus an
exposed ignition with command execution disabled that still flags and reports
the false flag.

verify: go test ./internal/modules, each matcher, anchor and extractor proven
to bite (break -> red, restore -> green).
