aish: package v0.1.0 for arch + debian

aish is an AI-augmented conversational shell in LuaJIT 2.x with FFI
bindings to libcurl, GNU readline, and libc — no C extensions, no
build step. Source-of-truth: git.reauktion.de/marfrit/aish, tag v0.1.0
(tarball sha256 9ebc3939e028832e39391ae33efacb5ec9bcd99d123cbc8ca1cd6ca9a640b5b5).

The arch and debian recipes mirror the lmcp pattern (pure-Lua any-arch
package, no makefile, install copies modules directly):

  arch/aish/PKGBUILD           — depends=(luajit readline curl)
  debian/aish/build-deb.sh     — pure dpkg-deb, SOURCE_DATE_EPOCH pinned
  debian/aish/debian/{control,changelog,copyright}

Install layout, matching what main.lua's script-dir-relative package.path
expects after the wrapper execs `luajit /usr/share/lua/5.1/aish/main.lua`:

  /usr/bin/aish                              ← bin/aish wrapper
  /usr/share/lua/5.1/aish/{main,broker,context,executor,history,
                           mcp,renderer,repl,router,safety,secrets}.lua
  /usr/share/lua/5.1/aish/ffi/{curl,libc,pty,readline}.lua
  /usr/share/lua/5.1/aish/vendor/dkjson.lua
  /usr/share/doc/aish/{README.md,LICENSE,examples/config.lua}

CI: two new jobs in .gitea/workflows/build.yml at the end of file.
aish-any chains needs:lmcp-debian (parallel-DAG with claude-his-any,
serialized via the shared arch-aarch64 runner — avoids needless wait
through the unrelated fourier stack). aish-debian chains needs:aish-any.
Both invoke the standard check-already-published.sh fast-skip on no-
change pushes.

Sonnet review (per feedback_reviews_use_sonnet.md + bugfix-process
step 4): no blockers. Folded in two findings before commit: switched
needs: from mpv-fourier-aarch64 to lmcp-debian (cleaner DAG, faster
cold-build wall clock), removed the dead Build-Depends: debhelper-
compat line from debian/aish/debian/control (build-deb.sh doesn't
use debhelper).
