build: make smartmoneyconcepts an extra and drop the <3.14 cap

`requires-python` capped Python at <3.14 because smartmoneyconcepts pulls
numba -> llvmlite, and llvmlite had no cp314 wheel. Two things are now
true that were not when that cap was written:

- llvmlite 0.49.0 does ship cp314 wheels (macOS arm64, manylinux x86_64
  and aarch64, win_amd64, win_arm64), so the cap blocks 3.14 everywhere
  for a reason that no longer holds;
- llvmlite ships no macOS x86_64 wheel at all from 0.46 on (0.45.1 is the
  last, cp310-cp313), so Intel Macs hit a cmake source build on *every*
  Python version. That is the failure in discussion #1035, and the cap
  never addressed it.

The cap also backfired: only 0.1.13 carries it, so on 3.14 pip backtracks
to 0.1.12 and installs the very thing the cap exists to prevent.

smartmoneyconcepts is imported by exactly one file, the skill example
src/skills/smc/example_signal_engine.py, whose SKILL.md already told the
reader to install it. Nothing else imports numba, and no test depends on
it. Every other extra (pyharmonics, statsmodels, arch, baostock, pykrx,
openbb-ai, langchain-anthropic) is already absent from agent/requirements.txt
and the lock, so this just brings smartmoneyconcepts in line.

Verified on a throwaway CPython 3.14.4 venv: base install carries neither
numba nor llvmlite nor smartmoneyconcepts, `vibe-trading --version` runs,
and the suite is 10774 passed / 23 skipped / 0 failed under CI's own
extras ([dev,openbb,stats]). The regenerated lock differs by exactly the
three removed packages, with no incidental version bumps, and still passes
`pip install --dry-run --require-hashes` on 3.11.

Note for CI: the test job pins python-version 3.11, so 3.14 is now
supported but unexercised.
