Goal

Fix system dependency detection in deps.lua for Lua libraries whose
package/display name differs from their require() name.

Context

module.conf declares system dependencies by package/display name
(e.g. luasocket, luaossl, luasec), matching what
tools/build-stpkg.sh and print_entry() show to the user. deps.lua
checks presence via find_lua_lib(name), which currently only
normalizes one specific case (lua-sql-* -> luasql.*).

For luasocket, luaossl, and luasec, the actual require() name
is socket and ssl respectively -- neither matches the declared
name, and neither is covered by the existing normalization. Result:
deps.check() reports these as missing even when installed (confirmed
on karl: lua54-socket and lua54-sec both present via pacman,
daw-module-smtp install still failed with "unmet system
dependencies").

Acceptance Criteria

deps.lua can resolve package/display name to require() name
for at least luasocket -> socket, luaossl -> ssl,
luasec -> ssl, alongside the existing lua-sql-* case
Approach is generic enough for future one-off cases, not another
hardcoded special case per dependency
daw-modul-smtp installs cleanly via bin/<project> modules install smtp once fixed (regression check)

Notes

Found while installing daw-modul-smtp into kaupapi. Worked around for
now via modules install-local <path>.stpkg, which skips deps.check()
entirely.

## Goal Fix system dependency detection in `deps.lua` for Lua libraries whose package/display name differs from their `require()` name. ## Context `module.conf` declares system dependencies by package/display name (e.g. `luasocket`, `luaossl`, `luasec`), matching what `tools/build-stpkg.sh` and `print_entry()` show to the user. `deps.lua` checks presence via `find_lua_lib(name)`, which currently only normalizes one specific case (`lua-sql-* -> luasql.*`).
