fix(build): strip comments from generated executables

[ScriptedAlchemy]

Why

Generated executables compiled with output.minify: false, so Rspack kept every comment from every bundled dependency. For Effect v4 that meant full JSDoc with import … from "effect" examples, 52 to 61 percent of each cargo-hauler bin, and text that reads like unbundled externals.

composeEntryLibConfig now runs the SWC minimizer only to drop comments. compress, mangle, and SWC's whitespace minify stay off, so the output keeps its formatting and names. legalComments: 'inline' now takes effect and keeps /*! … */ license headers.

Closes #860

Scope

• packages/agent-bundle/src/build/rslib.ts. The executable profile sets minify.js with minimizerOptions: { compress: false, mangle: false, minify: false }. The one-use generatedExecutableLegalComments export is inlined.
• packages/agent-bundle/tests/build.test.ts. The hatch test that injects a broken banner now injects it at PROCESS_ASSETS_STAGE_REPORT. At the default stage the minimizer rejects it before the AB6005 walk the test exists to prove.
• packages/agent-bundle/tests/self-contained-bundler-config.test.ts. The real build test asserts the shebang, formatted output, a kept /*! header, dropped fixture and yaml JSDoc, and runs the bin. The config-constant test is removed.
• website/docs/{en,zh}/reference/configuration.mdx and docs/framework-mode.md describe the new output.

Tradeoffs

The issue proposed format: { beautify: true }. Rspack 2.2.3 documents beautify as a no-op for its SWC minimizer, and a probe build collapsed to a 123 kB line. minimizerOptions.minify: false keeps SWC's formatted codegen instead.

Blast Radius

Every generated executable changes bytes, so artifact digests change on the next build. Code is not compressed or renamed, and authors can restore comments with tools.rsbuild.output.minify: false.

Verification

• Probe bin importing effect and yaml: 1,598,260 → 851,744 bytes, 930 → 0 commented from "effect" lines, same stdout, 17,236 formatted lines.
• Probe build time with and without the minify pass is unchanged (509 to 786 ms before, 526 to 706 ms after, interleaved).
• pnpm test at load average near 200. Unit passed 4,295 of 4,296; the one timeout (playground-service) passed on rerun. Route-unit and projection passed. Integration passed 1,155 of 1,164. build.test.ts exposed the banner-stage issue above, fixed and green (38/38). The other eight passed on rerun except examples-real.e2e "drives the host-test routes", which fails the same way on untouched main in the same four-file run.
