fix(gc): restore the raw-handle debt baseline after #7693

[proggeramlug]

fix(gc): restore the raw-handle debt baseline after #7693, and convert four pairs to pay for it.

#7693's regression test asserts a sentinel's pre/post address comparison — which is precisely what across_* exists to make unnameable, so converting its four reads would delete the test's subject. It joins json_shape_template.rs as the second instance of that permitted shape.

raw_handle_debt_files.txt allows listing only when the same change converts enough pairs elsewhere that the global baseline does not rise. Four converted, each a genuine read-after-allocating-call:

• os.rs — js_object_alloc_with_shape + the times re-read (ceiling 4 → 3)
• util_parse_args.rs — js_string_from_bytes + the values re-read (20 → 19)
• weakref.rs — entries_array (itself allocating) + the entry re-read (7 → 6)
• regex/match_all.rs — build_match_all_groups_owned + the inner-array re-read (14 → 13)

Net 998 → 998, 110 modules within ceilings.

Also converts three weakref.rs js_string_from_bytes + registry-re-read sites to across_nanbox. Those do not move the counter — it matches only .get_raw_{mut,const}_ptr — but they are the same defect and the same fix, and leaving them because they are invisible to the ratchet would be optimising for the metric.

📝 Walkthrough

Walkthrough

The runtime now refreshes movable pointers across allocation-triggered GC activity. Raw-handle debt ceilings and changelog records were updated. Workspace version references were incremented from 0.5.1398 to 0.5.1399.

Changes

Raw handle debt reduction

Layer / File(s)	Summary
Refresh pointers across allocation crates/perry-runtime/src/os.rs, crates/perry-runtime/src/regex/match_all.rs, crates/perry-runtime/src/util_parse_args.rs, crates/perry-runtime/src/weakref.rs	Runtime allocation paths use across_mut or rooted-handle re-reads before accessing movable objects.
Update raw-handle debt baseline scripts/raw_handle_debt_files.txt, changelog.d/7704-raw-handle-debt-after-7693.md	Debt ceilings were reduced for updated runtime files. A three-handle allowance was added for fs_options_object.rs, and the baseline remains 998 handles across 110 modules.
Update version metadata Cargo.toml, CLAUDE.md	The workspace and documented version were updated to 0.5.1399.
