fix: preserve Helm chart prerelease mode

[jayesh9747]

Summary

• use the app version only to select stable or prerelease mode
• keep the chart numeric core and RC counter independent from the app version
• start a chart prerelease at rc.0 and advance from the latest chart RC on main or the open chart PR
• stabilize the in-progress chart core when prerelease mode ends, then resume patch bumps
• preserve a reviewed higher chart core from the open chart PR

Expected lifecycle:

0.1.5 → 0.1.6-rc.0 → 0.1.6-rc.1 → 0.1.6 → 0.1.7

Validation

• pnpm test:chart-version
• pnpm format:check
• git diff --check

Closes #384.

Note

Medium Risk
Changes release automation that sets published Helm chart versions; behavior is covered by new tests but mistakes would affect OCI chart tags.

Overview
Fixes chart release versioning so prerelease app builds get matching -rc.N chart versions instead of only patch bumps on stable cores.

The build-and-prepare-chart-release workflow no longer inlines semver math and PR-branch comparisons. It still reads the open release-chart/trueforge branch for a reviewer-bumped version, then delegates to scripts/resolve-chart-version.sh, which picks the numeric core (patch bump from stable main, hold core across RCs, stabilize when the app goes stable), uses app version only for stable vs prerelease mode, maintains a chart-local RC counter (not tied to the app’s prerelease suffix), and keeps a higher core from the open chart PR.

Adds pnpm test:chart-version and shell tests covering stable bumps, RC progression, stabilization, and preserved PR cores.

@chiragjn let me check

My bad — I had addressed the review comments locally but had not pushed the changes. The requested updates are now pushed in commit 5a34ee2, and both review threads have been resolved. Could you please take another look?
