Rename make_superblock → superblock, make_inode_buf → inode_buf,
make_image → image, make_key → key in squashfs and streaming-aead.

Standardize fuzz and test conventions across 30+ packages:

- E715/E718: Add fuzz.ml runners referencing Fuzz_*.suite instead of
calling Fuzz_*.run() directly; update dune files accordingly
- E725: Fix fuzz_paseto suite name from "crowbar" to "paseto"
- E600: Create .mli interfaces for test modules (test_firmware,
test_remoteproc, test_pbkdf2, test_paseto) with single-group suites
- E605: Add missing test files (test_skills, test_monitor, test_openamp,
test_xrpc_server) with proper module extraction from inline test.ml
- E415: Add pp pretty-printer to xrpc_server type t
- E405: Add doc comment for pp_sync_action in skills.mli
- E205: Replace Printf with Fmt in fuzz_paseto and gen_corpus
- E331: Rename make_key to key in fuzz_paseto

- Change `run` signature to `string -> (string * test_case list) list -> unit`
matching Alcotest's grouping convention
- Fix `_name` bug: pass the name through to Alcotest.run_with_args
- Each fuzz module now exports `let suite = ("name", [test_case ...])`
- Entry points (fuzz.ml) collect suites: `Crowbar.run "pkg" [Fuzz_X.suite]`
- Remove stale `add_test`/`suite` API, keep only `test_case`/`run`
- Remove `let run () = ()` from fuzz_common.ml files
- Update merlint E725 rule to match new `let suite = ("name", ...)` pattern
- Update E725 test fixtures and expected output

- Restore cursor on exit via at_exit in Tty.Progress (fixes TTY corruption)
- Install SIGINT handler in monopam test for clean Ctrl-C
- Add 2s per-iteration timeout and 2s total budget to crowbar
- Group crowbar alcotest output by module prefix ("mdns: foo" → group "mdns")
- Skip fuzz runtest in afl context (enabled_if <> profile afl)
- Add merlint E725: enforce "module: description" fuzz test name convention

Add (enabled_if (= %{profile} afl)), (source_tree corpus), and
gen_corpus.exe deps to all 25 fuzz directories

E722: Convert ocaml-crc (test ...) to (executable ...) with rules
E718: Add gen_corpus.ml to ocaml-crc/fuzz
E724: Rename (alias fuzz-afl) to (alias fuzz) in 12 fuzz directories

Add doc comments to exported suite values in dupfind and ocaml-crc test .mli files.

Replace inline CRC-16/32 implementations in aos, bundle, cfdp, pid1, tc,
tm, uslp with shared ocaml-crc dependency. Fix ocaml-crc test formatting.
