Make the CI checks say how many files they actually read

Four checks in ci/ printed a reassuring line having examined nothing. Found
independently by the woo-ai-manager and woo-cache-manager sessions in their own
copies of this kit; all four reproduce here.

A check that examined nothing prints the same sentence as one that examined
everything, and only the passing side can tell them apart. That is why these
survived being verified: a pattern that is too broad fails loudly the first time
it meets real code, while one that finds nothing passes forever. So every
success line now carries a count — the old text domain line could not tell 142
from 0.

- static.sh, direct-access guard: counts what the loop examined and fails below
  MIN_SHIPPED_PHP_FILES. shipped_files() swallows a dist-files.sh failure with
  `|| true`, so an empty list is one broken .distignore away, and this is the
  check standing between a PHP file and being requested straight from a browser
  outside every capability check the code assumes has happened. The floor is
  above 1 because a pattern that wrongly excludes includes/ collapses the list
  without emptying it.

- static.sh, credential scan: counts what it read, fatal on zero. A pushed key
  is compromised even after the commit is deleted, so a silent no-op here is not
  a weak check but the absence of one wearing a green tick. The floor is 1 and
  is not configurable: this list has no filter that could go partially wrong, so
  the only way it misreports is by coming out empty.

- check-textdomain.php: three zeros, three verdicts. No PHP files at all is
  always fatal and deliberately not caller-configurable — it says the scan root
  is wrong, not that the plugin is small. Below --min is fatal. Zero calls with
  no --min is a warning, since a small plugin may legitimately have no
  translatable strings, but it is never silent.

- check-textdomain.php: fix the annotated path. str_replace( $root, '', $path )
  with the default root of "." removed every dot anywhere in the path, so a real
  error in includes/class-db.php was reported on "includes/class-dbphp" — not a
  file, not clickable, and not greppable. Every error this script printed with
  the default root was mangled that way.

The floors live in ci/plugin.conf, the only file under ci/ that knows anything
about this plugin, rather than hardcoded in static.sh: static.sh is copied
verbatim between plugins too, so a number in it would make this plugin's shape
everybody's constraint. ci_load_conf now requires them — an unset floor turns
its comparison into a no-op and silently restores the bug.

Each floor was broken once and watched to fail before being believed: empty
shipped list, wrong scan root, --min above the real count, zero calls without
--min, empty credential list, and a plugin.conf missing both floors. Static
checks green, and now report 13 shipped PHP files, 142 translation calls across
17 files, 44 tracked files read.
