chore: bump version to v0.3.2

[eddietejeda]

Summary

• Bump Cargo.toml version to 0.3.2
• Update Cargo.lock
• Add CHANGELOG entry for v0.3.2
• Bump all skill versions (hotdata, hotdata-search, hotdata-analytics, hotdata-geospatial) from 0.3.1 to 0.3.2

What is in this release

All bug fixes from PR #110:

• datasets create: add missing -o/--output flag; banner moved to stderr so -o json is jq-parseable
• sandbox new / update: move success banners to stderr for clean -o json output
• sandbox read: fix missing trailing newline
• sandbox delete: new subcommand; auto-clears active session when the deleted sandbox was the active one
• workspaces set: fix incorrect lock check (HOTDATA_WORKSPACE to HOTDATA_SANDBOX)
• context push: friendly hint when blocked inside an active sandbox

After merging

Tag v0.3.2 on the resulting merge commit to trigger the release workflow.

nit: (not blocking) The pre-release-replacements config in this file (line 68) lists README.md alongside the four SKILL.md files, but the README version badge wasn't bumped — it still reads version-0.2.7-blue (and was already stale at 0.3.1, so this predates this PR). Since this PR manually updates the same files that cargo-release would otherwise touch, it'd be a natural place to also bump the badge to 0.3.2 for consistency with the other version markers.

Good catch — fixed in 9e42d4d. Badge now reads 0.3.2. Also confirmed the dist-workspace.toml pre-release-replacements list includes README.md so cargo-release will keep it in sync going forward.

Version bump is consistent across all markers (Cargo.toml, Cargo.lock, README badge, four SKILL.md files) and the CHANGELOG entry accurately reflects the fixes from #110. Prior cycle's README badge nit is resolved.
