deps: update all dependencies to latest versions

[jongio]

Routine dependency refresh.

Updated dependencies:

• github.com/prometheus/client_golang: v1.23.2 -> v1.24.1
• github.com/ebitengine/purego: v0.10.1 -> v0.10.2 (indirect)
• github.com/klauspost/compress: removed by tidy (indirect, no longer needed)
• github.com/prometheus/common: v0.70.0 -> v0.70.1 (indirect)

Additional cleanup:

• Extracted status icon string literals to named constants in progress package (resolves goconst lint finding)

All tests pass. Build clean. Lint parity with main.
