Subject: [PATCH] fix(release): bump hard-coded version strings to 0.0.2 +
 route through MCPP_VERSION
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The v0.0.2 release.yml run produced a fully-functional musl-static
binary, but the smoke-test step rejected it because `mcpp --version`
still printed `mcpp 0.0.1`. The version literal had been hand-coded in
four places that the [package].version bump in mcpp.toml didn't reach:

  - src/toolchain/fingerprint.cppm:21  MCPP_VERSION = "0.0.1"
  - src/cli.cppm:64                    "mcpp v0.0.1 — ..." (print_usage)
  - src/cli.cppm:2805                  "mcpp 0.0.1"        (cmd_self_version)
  - src/cli.cppm:2874                  "mcpp 0.0.1"        (--version handler)
  - src/cli.cppm:2947                  .version("0.0.1")   (cmdline App ctor)

Bump the canonical constant in `fingerprint.cppm` to 0.0.2 and refactor
all five sites to read `mcpp::toolchain::MCPP_VERSION` so future bumps
only need a one-line change. The fingerprint constant already drives
the toolchain hash key, so its value matters for cache invalidation
anyway — this consolidates "what version am I" into a single
authoritative location.

Verified locally:
  $ mcpp --version
  mcpp 0.0.2
  $ mcpp self version
  mcpp 0.0.2
