scriptlib_resolve now lets an extensionless (or unknown-extension) lib:<name>
call match a file named exactly <name> when its first lines identify it as
tcl: a leading '# tcl' comment (prefix, case-insensitive), a shebang naming
tclsh/tclkit/wish, or the portable sh-trampoline ('#!/bin/sh' with a
commented 'exec tclsh' continuation - detected within the first 4 lines).
New internal punk::path::system::scriptfile_is_tcl does the bounded sniff
(512 bytes, UTF-8 BOM and CRLF tolerated, directories/unreadable files
rejected). When both <name> and <name>.tcl exist, the spelling matching the
call wins, checked per scriptlib location so kit-internal directory
precedence is never crossed by a spelling preference.
.kit joins the known extensions: lib:<name>.kit previously had .tcl appended
(searched <name>.kit.tcl), which made the shell subcommand's do_tclkit
dispatch arms unreachable - lib: kit dispatch is now restored. Result dict
reworked: scripttype (tcl/kit/py/pl/ps1/sh or empty) + notes keys added,
scriptname is now the matched relative name, and matches require file isfile.
app-punkshell and app_shellrun lib: handling refactored onto the shared
resolver (previously independent inline copies of the policy), fixing two
silent-failure bugs in that copy: no message at all when a scriptlib dir
existed but lacked the script, and the error listing showing
<kit>/scriptlib rather than the <kit>/app/scriptlib actually checked.
app-punkscript's post-resolve gate now uses scripttype and its not-found
report includes the identification skip notes. The unused has_globchars
vestige is dropped.
Fixtures scriptlib/_punktest/{extless,dual,dual.tcl,shebang_sh,notatcl} and
5 new scriptexec.test cases (extensionless resolve, both precedence
directions, trampoline shebang + argv, non-tcl skip note on not-found);
suite passes 17/17 against a freshly built punk902z kit. Sniff helper unit
checks pass under tclsh 9.0.3 and 8.6. punkshell project 0.13.0 -> 0.14.0.

Adds src/tests/shell/testsuites/punkexe/scriptexec.test (12 tests, all
pass) covering app-punkscript / the script subcommand (G-015): piped
execution and honest exit codes, error->exit 1, exitcode propagation,
stdin result echo, default-env dev alias present without boilerplate,
file-form argv passing, the lib:<name> scriptlib mechanism (subpath,
extensionless, bare-arg reclassification, not-found location listing),
and the tclsh-matching Tk main-loop behaviour (0.4.1): a serviced
after-callback runs and exits, a no-exit GUI script stays alive, an
errored GUI script exits promptly without hanging.
Reuses the shellexit.test built-exe harness pattern (pipe stdin,
half-close for EOF, timeout+force-kill) so runs are hang-proof; Tk cases
gated by an auto-detected punktk constraint (probes whether the kit loads
Tk). Full shell suite: 19 pass / 2 skip (console-only punkgoals) / 0 fail.
lib:/Tk cases resolve committed fixtures under scriptlib/_punktest/ - a
lib:-resolvable fixture cannot live in a tcltest temp dir since resolution
only searches scriptlib locations relative to the exe. The subfolder is
test-owned (README + do-not-edit fixture headers); root AGENTS.md carves
it out as the one agent-manageable exception to scriptlib being
user-only. No project version bump - tests/docs/fixtures only, no shipped
shell behaviour change.
