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.

app-punkscript accepts lib:<name> (with or without .tcl - extensionless
appends it) as the shell subcommand does: `punkexe script lib:hello` or
bare `punkexe lib:hello` via reclassification. The prefix always wins; a
literal path beginning lib: (pathological - colon is illegal in Windows
filenames) is reachable via ./lib:... Not-found errors list every
searched location; only .tcl runs via the script subcommand.
Resolution policy is factored into punk::path::scriptlib_resolve
(PUNKARGS-documented) rather than copied inline: kit-internal
app/scriptlib first and deliberately not externally overridable, then
scriptlib dirs relative to the executable - the same policy
app-punkshell encodes inline (todo noted: refactor the shell path onto
the shared proc). Share definitions via modules, not launcher control
flow.
Verified on both generations (punk902z, punksys): lib:hello
extensionless and explicit, bare-arg reclassification, not-found
candidate listing (bin/scriptlib then <root>/scriptlib for a bin/ exe).
Project version 0.4.0 (backward-compatible behaviour addition).
