chore: release MiniMax Code 0.5.3

[hetaoBackend]

Change

Bump the root and TUI package versions from 0.5.2 to 0.5.3 on top of main at 18e72783a8c25c1cf9dad89859a8ac9417e47cce. The annotated v0.5.3 tag points to this version commit and triggers the CLI archive release workflow. Merge this PR through normal review to carry the released version back to main; do not move or recreate the tag.

Validation

• PASS: pnpm install --frozen-lockfile, git diff --check, and full pnpm verify on clean commit 0f77d3306dac90604362da168a55f63a3ebad095 (macOS arm64, Node 26.4.0): all 15 applicable gates passed.
• PASS: node dist/cli.js --version reports 0.5.3.
• Performance: basic; only the two version fields changed.
• NOT RUN locally: Windows, Linux, release archive installation, and live services. The tag workflow performs Linux/macOS archive installation across supported Node versions before publication.
• Known base CI limitation: main Source verification run passed Linux/macOS but failed the Windows contract because npm pack timed out at test/windows-contract.test.mjs:54. This version-only change does not fix that failure.

Publication and contribution checks

• Permission to contribute under the existing applicable licenses; no imported material.
• No credentials, account data, real user content, internal history or private review material.
• No added/removed source files or new tests; inventory regeneration is not required.
• No shared documentation changes required. Offline checks are not live-service acceptance.

Maintainer handoff

Publication scope: tag-triggered GitHub CLI archive only; no npm registry or official installer publication. Shared-source port: not needed for this public release version metadata.
