feat(buglog): one Markdown record per bug, checked against a record standard

The buglog was one 27K-line JSON file whose fields covered only symptom,
root cause and fix, as free text: 2% of entries named the code version a
bug was found on, 12% the build profile, 36% a way to reproduce, and 58% of
the file was OpenWolf hook auto-detections ("Missing guard clause",
"Function not marked async" on .md files).

- .claude/skills/buglog/bug-record.md: the record standard. Eight
  sections (Summary as the title, Description, Environment, Reproduction;
  Root cause, Fix, Verification, References once fixed), each with the
  content it must contain -- e.g. Environment needs the OS, the libc the
  failing binary loads (from its ELF interpreter: glibc 2.42 in the nix
  shell vs 2.40 on the host), toolchain, build profile and commit.
- .wolf/bugs/<id>.md: 500 records migrated from buglog.json; every field
  verified to round-trip. They carry legacy: true and an explicit "not
  recorded" where the old log had no such field; component derived from
  file paths, severity from keywords (else unknown), fix_commits from
  hashes in status_note/fix that git resolves (91 of 463 fixed).
- .wolf/buglog-archive.json: the 710 hook auto-detections, verbatim.
- .wolf/buglog.json is now an index generated from the records, keeping
  the fields OpenWolf's hooks and `openwolf bug search` read.
- scripts/buglog.py rewritten: new (template + Environment collected from
  the machine and --binary), check, status (refuses a status the record
  doesn't support; fixed needs Root cause, Fix, Verification and
  --commit hashes git resolves), note, recur, set, show, list, triage,
  env, index. 29 unittest cases in scripts/tests/test_buglog.py.
- scripts/git-hooks/pre-commit runs `check --staged`: incomplete staged
  records, a legacy record hand-changed to fixed without the fix-time
  sections, a new record claiming legacy: true, or a stale index refuse
  the commit.
- scripts/gitea-sync.py reads the records: issue body = the record's
  sections plus linked fix commits (origin remote, GITEA_COMMIT_REPO to
  override), and a body hash so an issue's text is refreshed when the
  record changes.
- bug-1866 rewritten to the full standard as the worked example.

+# bug-1766: c source: sched_make_compound_allocation() does not roll back already-succeeded primaries when a…
+
+## Description
+OPEN, NOT A CRASH -- discovered while reviewing the scheduler-allocation spec requirements against live scheduler.c source: sched_make_compound_allocation() does not roll back already-succeeded primaries when a LATER primary in the same COMPOUND resreq fails allocation, and its own post-loop code can misattribute a partial allocation to a failed compound.

+## Reproduction

+
+## Root cause
+sched_make_compound_allocation() (src/scheduler/src/scheduler.c:206-238) loops over a COMPOUND resreq's primaries, calling sched_make_primary_alloc_(sched, &ctx) for each with ONE shared ctx across the whole loop. On a mid-loop failure (rc <= 0) it just `break`s -- it never undoes the primaries that already succeeded (no zeroing of ctx.alloc, no reversal of any resource state those primaries touched). Worse: seqjob/parjob's job_alloc_fn sets ctx->alloc directly on success (see seqjob_allocator.c my_alloc()), so if primary 1 of a 2-primary compound succeeds (leaving ctx.alloc non-NULL) and primary 2 then fails, the function's unconditional post-loop `if (ctx.alloc != NULL) { MOVE_PTR(obj->alloc, ctx.alloc); }` still fires regardless of the overall `rc <= 0` -- so a COMPOUND job that is reported as allocation-FAILED can still end up with obj->alloc set to primary 1's partial, orphaned allocation. requirements.md for scheduler-allocation (Req 9 AC2) had assumed, based on the sibling scheduler-framework brief's own text, that this path already 'tracks allocations in ctx and cleans up on failure' -- that claim does not hold against the actual code; requirements.md was corrected during this review. Not yet confirmed whether the orphaned ctx.alloc is ever read for a job later found to be PEND/failed (i.e. whether this is dormant/leak-only or produces an observably wrong result) -- not investigated further since it is out of the scheduler-allocation spec's own boundary (Req 9 AC2 explicitly freezes COMPOUND/ALTER dispatch as unchanged).
+
+## Fix
+NOT FIXED -- out of scope for the scheduler-allocation spec (which explicitly leaves COMPOUND/ALTER dispatch unchanged, Req 9 AC2) and no other spec currently owns sched_make_compound_allocation(). Discovered only because scheduler-allocation's own NEW per-plan rollback (Req 4's rollback_plan_allocation(), for the parjob multi-host-bucket case) needed a reusable precedent to model itself on; this path was found not to provide one. Needs its own follow-up: likely either (a) track which primaries in the compound loop actually succeeded and explicitly free/clear their contribution to ctx.alloc before returning on a later failure, or (b) defer the MOVE_PTR(obj->alloc, ctx.alloc) until the loop confirms overall success, freeing ctx.alloc on the failure path instead. Whether this ever produces an observably wrong result (vs. a dormant orphaned pointer) is unconfirmed and should be checked first.
