TapTap 34abaadb9a fix: address low/informational sec-parser follow-ups
- client_cli: capture errno before output_escape() in
  read_patterns_from_file() so an over-long line is still reported as
  EFBIG instead of the (possibly malloc-clobbered) errno.
- file_list: guard string_list_add() capacity doubling against
  overflow (capacity > INT_MAX / 2), matching filter_rule_list_add();
  callers already surface the false as a memory-allocation error.
- compression: ZSTD_isError() is true for ZSTD_CONTENTSIZE_UNKNOWN,
  which made the 3x unknown-size fallback dead code.  Test the
  CONTENTSIZE_ERROR/UNKNOWN sentinels explicitly so unknown-size frames
  reach the estimate path (still bounded by the existing hard limit)
  while invalid frames are rejected.  Known-size frames and the 100 MB
  ceiling/overflow checks are unchanged.
- tests: add an unknown-content-size-frame decompression test.

Tests: ./build/tests and ./build-asan/tests all pass (42/42);
clang-format + cppcheck clean.

TapTap 1a26bde2d4 fix(file_list): bound entry length and reject embedded NUL bytes
Read list files through utils_getdelim_bounded() so a single multi-gigabyte
line can no longer force unbounded allocation; over-long entries fail with a
clear error.  Also add the documented memchr() NUL-byte check (excluding the
NUL delimiter in NUL-separated mode).

Tests: an over-long entry is rejected with an 'exceeds' diagnostic.

TapTap 7f2180ef90 fix: filter precedence, files-from errors, NUL/CRLF and filter-rule rejections
Address an independent c-review of the files-from/filter feature:

- .rsync-filter precedence now matches rsync: evaluate the innermost
  (current) directory's rules first, then ancestors, then the command-line
  base (--filter/-C), so a deeper file's '+' can re-include what a shallower
  '-' excluded (regression tests in both scan modes; single-thread and -m).
- --files-from: a listed entry missing on disk and an empty list are now hard
  errors surfaced pre-transfer in send_files, send_files_multithreaded,
  dry-run and --list-only; '.' (whole tree) and empty listed dirs stay valid.
- scanner_path_relative now handles a transfer root of / (previously the
  scanner aborted on children of /).
- Reject unsupported rsync filter syntax explicitly (no silent no-ops):
  +/- modifiers other than '/' (! C s r p x) and rules beginning with ':'/'.'
  /'!' (merge/dir-merge/list-clear shorthands). Docs updated.
- -0/--from0 NUL mode preserves entry bytes (no CR/LF trimming); only newline
  mode trims. Absolute-entry error message no longer includes the newline.
- --no-from0/--no-cvs-exclude registered as negatable booleans.
- RSYNC_COMPAT rows updated for the precedence, rejection list, NUL-mode
  detail and the documented O(entries x files) scalability bound of the
  allow-set (Summary unchanged: 62/3/5/1/76 = 147).

Implement the RSYNC_COMPAT Phase-2 filter/parser feature group:
- --files-from=FILE (repeatable) plus -0/--from0 NUL delimiters: parse the
  source file list relative to the source root into a shared read-only
  allow-set; the scanner transfers listed files and the whole subtree of
  listed directories and prunes everything else in single- and
  multithreaded mode. Absolute/'..' entries and missing files are hard
  CLI errors.
- --filter=RULE: rsync-style +/- rules (anchored '/', dir-only trailing '/',
  word include/exclude forms) evaluated first-match-wins with a default of
  include, as an independent layer from legacy --exclude/--include.
  Unsupported directives (merge/hide/... ) are rejected explicitly. -f stays
  sendfile.
- -C/--cvs-exclude: well-known rsync CVS default exclude set.
- -F: per-directory .rsync-filter files read during traversal and applied to
  the owning directory's subtree (single + parallel), never transferred.
- Delete manifest still derives from what was actually sent.

Client-only config fields; no wire/protocol change. Adds unit coverage
(CLI parse, allow-set and filter scanning single+parallel) and integration
tests (TestFilesFrom, TestFilters). RSYNC_COMPAT matrix rows updated:
5 rows move to Implemented (Summary 62/3/5/1/76 = 147).
