This saves gossipd from converting it:
```
lightningd-1 2026-02-02T00:50:49.505Z DEBUG gossipd: Time to convert version 14 store: 890 msec
```
Reducing node startup time from 1.4 seconds to 0.5 seconds.

It's used by common/gossip_store.c, which is used by many things other than
gossipd. This file belongs in common.

We also put this in the store_ended message, too: so you can
tell if the equivalent_offset there really refers to this new
entry (or if two or more rewrites have happened).

Our poor scid generation clashes badly with simplified hashing (the
next patch) leading to l1's startup time when using a generated map
moving from 4 seconds to 14 seconds. Under CI it actually timed out
several tests.
Fixing our fake scids to be more "random" reduces it to 1.5 seconds.

This commit introduces a modern coverage infrastructure for Core Lightning:
- Migrate from ad-hoc coverage script to integrated Makefile targets
- Add LLVM source-based coverage support with per-test profraw organization
- Integrate coverage collection into pytest framework via TailableProc
- Add GitHub Actions workflow for nightly coverage reports
- Add Taskfile.yml for convenient task automation
- Add codecov.yml for Codecov integration
- Add comprehensive coverage documentation in COVERAGE.md
- Update contributor workflow docs with new coverage script path
- Add coverage data files to .gitignore (*.profraw, *.profdata)
- Remove obsolete contrib/clang-coverage-report.sh
- Remove obsolete tests/conftest.py (now using pyln-testing markers)
- Update pyproject.toml to include pyln-testing in main dependencies
The new infrastructure automatically collects coverage data when CLN_COVERAGE_DIR
is set, organizing profraw files by test name for granular analysis.

I added amount_msat_accumulate for the "a+=b" case, but I was struggling
with a name for the subtractive equivalent. After some prompting, ChatGPT
suggested deduct.

No idea if it works, we don't test it and nobody runs it. I guess not.

Each header should only include the other headers it needs to compile;
`devtools/reduce-includes.sh */*.h` does this. The C files then need
additional includes if they don't compile.
And remove the entirely useless wire/onion_wire.h, which only serves to include wire/onion_wiregen.h.

This means we don't have to manually choose what to link against,
which is much of the complexity of our Makefiles: the compiler will
automatically use any object files it needs to link.
We already do this for ccan as libccan.a, now we have libcommon.a.
We don't link against it for *everything*, as some tests require their own
versions.
Notes:
1. I get rid of the weird plugins/test/Makefile2 (accidental commit?)
2. Many tests change due to update-mocks.
3. In some places I added the missing dependency on the Makefile itself, though most are in the next
patch.

Changes:
* Fields renumbered to their draft values + billion.
* offer_recurrence now comes in compulsory or optional (backwards compat) flavors.
* `proportional_amount` is now inside `offer_recurrence_base` not `offer_recurrence_paywindow`.
* New field `invreq_recurrence_cancel`.

Changelog-EXPERIMENTAL: Draft specification for recurring offers changed: old recurring offers will no longer work.
Offer_absolute_expiry should be used if you want to require starting at the start.
Changelog-EXPERIMENTAL: Protocol: BOLT 12 recurrence `start_any_period` removed, use expiry if you need to restrict when they can start using the offer.
This should detect partial writes more robustly, since we make a
separate pwrite() call to update this flag after the record is written.
Previously we were playing a bit loose with synchronization assumptions,
which seemed to work on Linux ext4, but not so well elsewhere.

The character classification functions in <ctype.h> are designed to
classify characters returned by <stdio.h> getchar() and friends, which
return characters as signed integers in the range 0 to 255 or EOF. The
behavior of the ctype functions is undefined if they are passed a value
outside of that range, which may happen if they are passed a char-typed
value and the system's char type is signed.
<ccan/str/str.h> defines some inline utility functions that perform the
necessary cast to coerce a char-typed argument into the allowed value
range. Call these wrappers instead of the bare ctype functions when
classifying char-typed characters.

To actually evaluate spend cost, we need to know whether it's taproot or not.
Using an enum (rather than making callers examine the script) means we can
ensure all cases are handled.

The old blindedpay fields would have an entry per hop, but that was changed
to a single per-path entry. The devtools hadn't caught up.
Similarly, it didn't like descriptionless offer fields in invreqs and invoices.

We only use it in one place, and that was simply to share an fd between
gossipd writing and gossipd reading, which may be causing our zfs problem
anyway.
