Distilled from #685 (nguyentamdat) rebased onto current main, plus two
research-driven refinements and a genuine reproduce-first guard.
The parallel extract retains each file's source text so the fused cross-file
LSP resolve can re-parse it. That retention is transient but a peak-RSS driver.
On main the caps are flat (100 MiB/file, 2 GiB total) and a file over the cap is
silently unretained AND its cross-file resolution is skipped -- a graph-quality
gap. This change bounds retention AND keeps every cross-file edge.
- Source-text cap as a FLOOR, not just a ceiling: retention total defaults to
min(cbm_mem_budget()/8, 1 GiB), per-file min(32 MiB, total). Following the
rust-analyzer memory model, the RAM-derived default is clamped to a small
absolute ceiling so a huge-RAM host does not hold tens of GB it would re-read
cheaply. Both caps env-overridable via CBM_RETAIN_TOTAL_MB /
CBM_RETAIN_PER_FILE_MB (limits.c convention); ceilings bound only the
auto-derived default, never an explicit operator/caller choice. A dropped file
emits one index.retain_capped WARN per run.
- Bounded re-read fallback (the correctness guarantee): resolve_worker re-reads
an unretained file's source on demand (bounded, freed immediately) instead of
skipping resolution, wired at every cross-LSP site that consumes source. The
cap now only trades retained RAM for a bounded re-read, never a lost edge.
- cbm_parallel_extract_ex + opts struct (cbm_parallel_extract is now a wrapper
passing NULL -> env-derived defaults); malloc/calloc NULL-check hardening.
Reproduce-first: parallel_cross_file_reread_preserves_unretained_edges uses a
Java<->Kotlin pair whose cross-file lsp edges are genuinely source-dependent;
the edges are lost when the caller is unretained and the fallback is absent
(RED), present with it (GREEN), with a retained CONTROL scenario proving
non-vacuity. #685's original Python red test was a false guard (per-file py_lsp
already resolves those calls) and is replaced. Peak-bound guards
(retained_bytes <= total_cap; retain_sources=false retains nothing) in test_mem.c.

Use 25% of physical RAM on hosts with 16GB or less, 35% on 32GB or less, and 50% above. Expose cbm_mem_ram_fraction_for_total() for unit tests and call it from MCP/CLI startup instead of a fixed 50% fraction.

Add scripts/check-no-test-skips.sh (run from lint) which fails the lint phase on any plain SKIP() or direct tf_skip_count manipulation; only SKIP_PLATFORM() (for genuinely platform-specific tests) is tolerated. Add FAIL() and SKIP_PLATFORM() helpers to the test framework and convert the remaining SKIP()/perf-gated skips across the suite into pass-or-fail assertions, so a suite that cannot meet its preconditions reports a red failure instead of a silent skip.
- cbm_mkdtemp: _mktemp + _mkdir on Windows
- cbm_setenv/cbm_unsetenv: _putenv_s on Windows
- cbm_pipe: _pipe on Windows
- Replace bare POSIX calls in 12 test files with compat wrappers
- All test files now include compat.h
